Hi,
So I have been using KDE since a week or so and I seem to have strange white lines quickly appearing and disappearing (horizontally). I did a full system upgrade. Note that I had the same problem in Pop OS KDE as well.
I first thought it was firefox, but then I switched to vivaldi and the issue remains. It is really strange. I have not tried to use gnome to see if the issue persists. Is there another solution?
