Description Piotr K 2020-06-03 17:49:29 UTC
I have serious problem with my laptop after suspend. Screen is randomly blinking when opening new window or scrolling in KDE with default kernel. Problem not persist in GNOME.

It happens only on one of my machines and only after wakeup from suspend.
Maybe there os something wrong with refresh rate after wake up? 

Problem is gone when i update kernel to 5.6, so I think this is a kernel 5.3 bug.

My hardware is: Huawei MateBook 13 (i7-8565U, GeForce MX150)

Could you run hwinfo (as root), and attach the output to Bugzilla?

JUst noticed that is also happens in GNOME but less often. Both of X11 and Wayland.

Piotr, I presume this is still a problem. Could you share the kernel log after the issue manifests itself, please?
