--- Comment #3 from mombelli.mauro@gmail.com --- I updated to 5.6.0-rc4-1-mainline, the problem persist. Also while running stable, seems like the issue is still present, just much less pronounced.
I notice sometimes is like a black line on screen.
I could bisect but maybe I should find a stable version, or maybe is related to the desktop environment. As I use kde, should i maybe check if it happen with gnome too?
