Request to verify a Bug

[GerhardErtl]

Dear Community,

I think I have found a Bug in Direct3d Shader Compiler for Intel 620,630 and 520 GPUs.  I also developed a small Test program to reproduce this bug. I already tried to report this Bug but I could not get Intel to look at it in Detail. They seem to think that there is an Error in my program, but I am quite sure that there is no Error since the program is very simple.

The test Program and detailed documentation of the Bug can be found in my Github project:

https://github.com/GerhardErtl/Intel630Bug

My Request is that someone with higher credibility than me clones this github repo, verifies that there is indeed a Bug and tries to get Intel to review it. This would be very helpful, since I can think of no other way to get Intel to work at this.

Many thanks in advance. If you can help me, I will pay you a beer.

Thank you for the update GerhardErtl. The Github page does not list the step-by-step guide to reproduce this error, we need that information to reproduce this issue in our labs. Let us know once you have the information to continue.

The Github Repository contains a description in the ReadMe. Here is  a copy:

1) Clone this repository

2) Open Intel630Bug.sln with Visual Studio 2019 or newer.

3) Compile in x64 Release Mode.

4) Run the program

Result:

If you are running on an Intel 620 or 630 GPU you see a flickering image when you move the mouse. If you are using a different GPU you see a yellow image.

The Yellow Image is correct. The flickering Image is wrong

You have not heard from me since you did not ask me anything. You just informed me what you are doing without requesting an answer. So I did not answer. Before you close this thread I would like to know how and if Intel is planning to Inform me of the Progress with Bug.
