This bug is awaiting verification that the linux- hwe-5.15/5.15.0-48.54~20.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'.
If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

But the panel starts to flicker like crazy on top of the new stable commits. [Fix] Backport full fix for PSR2 selective fetch, but only enable it on TGL + specific AUO panel. The last three patches which enable PSR2 on ADL-P are dropped. [Test] Originally the backport regressed ADL + BOE panel, so this time we put extra effort to ensure those system are unaffected, while TGL + AUO panel is still fixed. [Where problems could occur] Most code changes only have functional impact when PSR2 selective fetch is enabled. Some of changes are under more general call path for hardware cursor rendering. Notes are added to describe the functional impact for each patch, so if regression really occurrs it's easier to spot the offending commit.
