Commit 15512021eb3975a8c2366e3883337e252bb0eee5 (15512021eb3975a8c2366e3883337e252bb0eee5) causes a lof of white spots to appears on the right upper corner of all console screens (see https://drive.google.com/file/d/13GabEvOIKSAj5yox6ybAZEDu3Ixncw5Q/view). git-bisect shows that this is the offending commit and if I revert it, the problem goes away. The problem still occurs with kernel 5.18-rc2 and to all stable trees where it was applied. Can somebody explains what happens ?
The video card is the following: VGA compatible controller: Intel Corporation WhiskeyLake-U GT2 [UHD Graphics 620] (rev 02) (prog-if 00 [VGA controller])
Please tell me if you need more info.
Thanks in advance,
François Valenduc

That's commit 15512021eb39 ("drm/i915: Workaround broken BIOS DBUF configuration on TGL/RKL"), adding Cc's.
Please file a report at fdo gitlab [1] and attach dmesg etc. there.

That commit looks like it is just disabling all the planes, if wrong dbuf/wm configuration is detected. However it should do that only once during boot as I understand.
Are you sure that is exactly this commit which is causing this? Does the issue appear always?

Does it just happen all the time or some steps/certain circumstances needed for it to happen?
Only suspicion after looking briefly is that once suspend/resume is done it might be messing something up. Just a quick guess..
