Glitching when D3D11VA is used and D3D11 is rendered with semi-transparent pixels.

[pgorak]

Hello,

We want to report a serious bug in the latest drivers that causes strange glitches (please see attached screens). This problem occurs on ARC GPUs with latest Intel drivers and older DG1 GPUs like Iris Xe MAX.

A similar problem was reported last year here:

https://github.com/IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT/issues/1145

These guys reported that:

"Appears to be fixed in latest 32.0.101.8132 (WHQL Certified) graphics drivers. Thank you."

on Sep 29, 2025

Well, we are still are experiencing this issue in our Remotly software on the same drivers. You can replicate it by using our remote desktop and gaming software (remotly.com)

1. Download the installer and install it on the host and client machines

2. You will need an account to use the software so please create one

3. After connecting to a host machine when D3D11VA is used by the client side for video rendering/decoding and showing any OSD overlay that obscures the video (and has some semi-transparent pixels) the glitches start to occur.

Using older drivers which work (like 32.0.101.5869) is not a solution as many of our users and customers use new machines with latest Intel GPUs where they have newer drivers pre-installed. The only solution for them is to disable HW accelerated video decoding on client side which is not acceptable.

BTW. We have worked closely with Intel in the past when developing our Action! Game Recording and Streaming software (Mirillis company) and have some Intel prototypes in our labs. We have a DG1 desktop card (silver one) that also has this problem with drivers 32.0.101.7084.

What is strange is that the glitches do not appear when an overlay is rendered but when all overlays disappear and only the video is shown in full screen (borderless, works OK in window). So it is the reverse from what we are seeing on ARC GPUs.

A workaround to this problem is rendering a 2x2 pixel transparent texture over the video (magically the glitches disappeared).

Please do investigate this problem as it looks like a serious one.

Hello pgorak,

Thank you for raising this concern through the Intel Community.

I appreciate you providing the troubleshooting steps that you have already performed on your end. This information helps us narrow down the investigation. To further review the issue, I would like to gather a few additional details.

Please note that for DGPU1 (Intel Iris Xe MAX), the driver may not be listed separately. In this case, it is recommended to use the Intel® 11th–14th Gen Processor Graphics – Windows* driver package when updating your graphics drivers.

To help us better understand the situation, could you please clarify the following:

• How many units are affected by this issue? Is it occurring on multiple systems or only on the system in your laboratory?
• Do the graphical glitches occur only during remote sessions, or do they also appear when using the system locally?

Once this information is provided, I will be able to proceed with internal replication and further investigation.

Thank you for your cooperation, and I look forward to your response.

Hello John,

Thank you for your prompt reply.

"I appreciate you providing the troubleshooting steps that you have already performed on your end. This information helps us narrow down the investigation. To further review the issue, I would like to gather a few additional details."

We will do our best to help in resolving this problem.

"Please note that for DGPU1 (Intel Iris Xe MAX), the driver may not be listed separately. In this case, it is recommended to use the Intel® 11th–14th Gen Processor Graphics – Windows* driver package when updating your graphics drivers."

The DGPU1 we have in our labs is an Asus VivoBook 14 pre-production model. We are using drivers 32.0.101.7084 on this machine, which are the latest available for this GPU. This laptop has 2 GPUs: Intel Iris Xe Graphics, and Intel Iris Xe MAX Graphics. The glitching only occurs on the MAX GPU. As explained earlier rendering even 1 semi-transparent pixel in full screen in the client app (which is basically an ultra low latency video player that streams video from the remote host) fixes the problem. Also, not using D3D11VA for video decoding fixes the problem. No idea how this is possible but must something low-level.

Now going back to the ARC problem:

"How many units are affected by this issue? Is it occurring on multiple systems or only on the system in your laboratory?"

Problem is occurring on multiple production laptops with ARC GPU. I will ask me team to check whether it is occurring on desktop ARCs. From what I remember it is not occurring on UHD 770.

"Do the graphical glitches occur only during remote sessions, or do they also appear when using the system locally?"

The glitches have nothing to do with remote sessions. It is more of a client (video player) problem just like the one described in IGCIT/Intel-GPU-Community-Issue-Tracker-IGCIT/issues/1145 (link in available at the top of this thread).

We have zero problems with Intel Xe, Xe MAX and ARCs on the host side using SDR, 4:4:4 and HDR encoding. 

The problem is only visible on the client/receiving side.

I hope Intel can replicate and resolve this problem. If you'll need details on the D3D11 setup we are using, I'll gladly assist in that matter.

Hello pgorak,

Thank you for confirming that your system is currently using the latest drivers. However, I understand that the glitching issue still appears, particularly when using the MAX GPU.

To proceed with the internal replication of the issue on our end, could you please provide the link to the exact laptop model that you are using?

To further assist you, I kindly request that you download and run the Intel® System Support Utility (SSU) so that we can gather a complete overview of your system configuration.

Intel® System Support Utility for Windows*

Once the download is complete, please follow these steps:

1. Launch SSU.exe.
2. Click Scan and check the box Everything.
3. Click Scan.
4. Once the scan is complete, click Next.
5. Click Save and attach the file to your response.

Additionally, on the client or receiving side, could you please confirm if the graphics drivers are also updated? You may also try using a different remote desktop application to determine if the issue is related to the remote session itself. For testing purposes, you may try using Microsoft Quick Assist and check if the same behavior occurs.

Hello John,

Please find the logs attached:

1. iris_xe_max.txt - glitches visible on new drivers without forced alpha pixels rendered in full screen video (workaround)

2. Intellaptop.txt - glitches visible on new drivers when rendering D3D11 textured quads over video decoded using D3D11VA (Glitch_SDR.jpg attached screen)

3. rtx5090laptop.txt - glitches visible on new drivers when rendering D3D11 textured quads over video decoded using D3D11VA (Glitch_SDR.jpg attached screen)

Important: the glitches are not visible when streaming in HDR format and using new drivers! The difference between SDR and HDR in our product is that SDR uses BGRA8 back buffer and HDR uses R10G10B10A2 format (this might be useful information for you). See attached No_glitch_HDR.jpeg.

Glitches are also not visible in SDR and HDR using old 32.0.101.5869 drivers on the same machines (intellaptop.txt and rtx5090laptop.txt).

"Additionally, on the client or receiving side, could you please confirm if the graphics drivers are also updated? You may also try using a different remote desktop application to determine if the issue is related to the remote session itself. For testing purposes, you may try using Microsoft Quick Assist and check if the same behavior occurs."

Microsoft Quick Assist does not seem to use hardware acceleration on the client/decode side so this test makes no sense (our product also has no glitches when intel hardware decoding is not used and connection is done using H264 decoded in software).

Additionally this tool does not use end-to-end encryption and our policy restricts us from using this kind of remote connection in our labs. It is also not allowed by our customers.

Hello pgorak,

Thank you for providing the detailed information. Please allow me some time to review the text files and investigate the reason you experienced flickering in SDR. I will also test this in our laboratory. Once the tests are completed, I will provide you with the steps for isolation.

Hello pgorak,

Thank you for your patience while we worked on isolating the issue.

At this stage, I recommend trying the following workarounds:

• Use the OEM-provided graphics driver for each affected system.
• If you need to switch drivers, please perform a clean installation using Display Driver Uninstaller (DDU) before installing the OEM driver.
• If the issue persists with the OEM driver, please test using the latest generic driver version Intel® Arc™ Graphics - Windows*.

Once you have completed the steps above, kindly provide an update on the results so we can continue the investigation if needed.

We appreciate your cooperation and look forward to your feedback.

Hello John,

Unfortunately none of the above steps helped. After installing latest OEM-provided graphics drivers or the latest generic driver issue still persists in SDR mode (DDU was used before installing both OEM and latest generic driver).

After rolling back to 32.0.101.5869 everything works fine.

[JohnM_Intel]

Hello pgorak,

Thank you for letting me know that the issue still persists after following the steps I provided, and that rolling back to version 32.0.101.5869 resolved the issue. I appreciate the details.

To further investigate, could you please confirm whether the older driver you used is an OEM driver or a generic Intel driver?

Additionally, could you share the link where you downloaded that driver so I can test it internally?

Hello John,

Sorry for the late response.

"To further investigate, could you please confirm whether the older driver you used is an OEM driver or a generic Intel driver?"

I think the older driver was a generic Intel driver (link below).

"Additionally, could you share the link where you downloaded that driver so I can test it internally?"

Please find the source of the older driver (32.0.101.5869) which works without issues below:

Hi Enrico,

Thank you for joining this thread.

Please let me know if you need more details or step by step instructions on how to replicate the problem when switching from 32.0.101.5869 to latest drivers and back.

[JohnM_Intel]

Hi pgorak.

I have tested the unit on our end, but we were unable to replicate or encounter the issue you described. To help us investigate this further, could you please provide the exact steps to reproduce the issue? If possible, a short video demonstrating the problem would be very helpful for our investigation.

Additionally, we tested the unit on both a laptop and a desktop using Intel graphics and did not observe any glitching. Could you also confirm if you have tried using the OEM (original equipment manufacturer) drivers for your laptop? These drivers are typically more optimized for your specific system and may help resolve the issue.

We appreciate your cooperation and look forward to your response.
