--- Comment #35 from Fonic <fonic.max...@live.com> --- And I can confirm that downgrading of the nvidia driver actually works. In my case, I downgraded to 440.100 (latest stable version of 440 branch on Gentoo Linux) and all issues are gone. When suspending/resuming now, - kscreenlocker works as expected - system settings works as expected - kwin (*) does not crash - there are no graphical glitches (*) Patch '0001-Use-glXGetProcAddress-for-context-creation.patch' *not* applied Gentoo Linux (amd64, stable) Linux Kernel 5.4.48 NVIDIA drivers 440.100 KWin 5.18.5 Qt 5.14.2 -- You are receiving this mail because: You are watching all bug changes.
