Martin Peres @mupuf said:

This issue is happening on Gen9+ platforms.

The Gen9 platforms issues might be because of https://bugs.freedesktop.org/show_bug.cgi?id=103191. So let's wait for this to be fixed before investigating more.

As for Gen11, the failure happens every single run, so we have a real issue. Arek will detail what the test is doing, and what are the next steps.

Arkadiusz Hiler @ivyl said:

The test first grabs reference CRC from a pipe with primary plane being filled with green.

Then, for each non-primary plane, it sets up the pipe the following way:

1. primary plane is green but with 64x64px black square at position 100x100
   
2. the non-primary plane is set to be 64x64xpx green square at position 100x100, basically covering the black hole
   
3. compare the CRC of fully-green primary to CRC of the setup with the hole covered
   

This kept failing for 7th(!) plane on all our ICLs, but it was last seen 2 weeks ago.

Martin Peres @mupuf said:

The ICL issue where the 7th plane is behaving differently is surprising and cause for concern. The user impact could be that some windows on some compositors exhibit a different behaviour as other windows. This would warrant the highest priority.

However, the fact that this issue has not been seen in 2 weeks / 120 runs after being 100% reproducible indicates that this was the fallout of another issue which has already been fixed. Because of this, I'm dropping ICL from the list of platforms covered by this issue.

I am also dropping the priority to medium, as this bug will need to wait on 103191 to be fixed before further investigation. There is no point in weekly check ups.
