Video showing flickers
Since a few days ago, I get severe screen flickering with black bars when I
start Krita 4.2.0 Next nightly build through primusrun (so that it uses the
dedicted GPU on my laptop) - before that it worked fine. If I then turn off
OpenGL accelerated canvas it disappears.
If I use optirun instead, there is no flickering issue.
There is also no flickering problem with primusrun in Krita 4.1.8, or any other
application I tested. Looking through my installed packages, neither the Nvidia
driver nor Bumblebee have been updated in this timeframe.
I attached a short video that shows it. Seems to be more severe in a maximized
window, but never goes away completely.
