Crash in latest Iris Xe drivers (31.x) when toggling fullscreen in D3D11

BleuBleuRB · ‎10-25-2022

Hi.

We are from a game development studio are experiencing a crash with the latest Iris Xe drivers on Windows 10/11.

The crash will happen on version (31.0.101.3430/31.0.101.2111) when switching between windowed/fullscreen, in Unreal Engine 4, in Direct3D 11. Direct3D 12 is fine. The crash does not happen in every single of our map, but for a given map, it is 100% consistent.

It happens on both a Dell 9305 and a Asus Vivobook.

Running with D3D debug layer gives this message when the crash happens.

xxx.exe has triggered a breakpoint.

The previous driver version (30.0.101.1994) does not suffer from this issue, leading me to believe this is a regression in the latest driver.

We are also on a deadline and would like to be able to contact developers directly.

Hi Mat,

I will contact with the drivers team to review your case.

How do you guys change from windowed to full screen? Alt+Enter? or is it an option inside your game?

Also please use the latest drivers (31.0.101.3729/31.0.101.2114) from here

I will need more details that the SSU tool can provide, please run it and share the log files.

Hi.

Just tried the latest drivers. Same issue. I mostly do ALT-Enter, but inside out setting menu will make it crash too.

Here are the files. They are from few days ago and might be when i was trying different driver version, but it should be good enough.

Hi @BleuBleuRB

Thank you for sharing the logs, we will do a -similar test- on our end to confirm issue reproducibility in Unreal 4 with the latest driver

Will get back to you soon in case we need more info

Hi @BleuBleuRB

We are already trying to reproduce the behavior, but we have a few questions

What makes that map different from the others where the issue is not happening?

Appreciate the help

Hi.

Yeah this is where it gets complicated. It tends to happen on "heavier" maps. For example, we don't get it in the main menu or our tutorial map. But real production maps do reproduce the crash.

We'll have an open Beta starting tomorrow (the 29th) mid-day, until Monday (i think). Follow the link, press "Request Access".

You'll likely have to play the tutorial and reach the "Police Station" map to get the crash.

If this is too tedious, we could probably set you up with a special build that directly starts on a problematic level.

Hi Mat

Thank you for sharing it!

However if you could give us earlier access to it we'd get hands on faster. We have no problem on using the Beta until it is officially released (It is still Oct 27th for us) but I think the special build will be best, the fastest we can replicate the issue, the better

I will be sending you a separate message for this
