Thanks a lot for you patch! I've noticed as well that amdgpu ignores the plane alpha property [1]. I'll try to find time to test it.

Hi Simon,

So you've faced this kind of issue many times :/ Let me know the results from your side, so we can use it to find the correct approach to solve this issue.

Yeah, it looks like the same problem.

I also think the IGT test case (alpha-7efc) is not the best one because results can be affected by rounding issues. Maybe the test should be reworked, but first this alpha property issue should be clarified.

Thanks for the inputs!
