Hi,

Is it possible to upload the failing video?

Can you please check kernel log and see gfx driver enables PSR2 or PSR1?

Experiment:

• Is it possible to please try i915.enable_psr=1 and see if still failing?

• Is it possible to please try i915.enable_psr=0 and see if still failing?

Thank you so much!

It’s not reproduced after appending “xe.enable_psr=0“
