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
