Hello,
after upgrading leap 15.4 to 15.5 and now 15.6 on my laptop I see a very
light flickering on my LCD-screen and some very small horizontal streaks. When
I move the mouse or when I start VLC to watch TV there is no flickering and
the streaks disappear. Going back to 15.4 everything is fine. When I start my
session with IceWM or TWM also everything is OK, but with plasma (X11) or
plasma (Wayland) there is this light flickering.
Any idea what is wrong?
