flicker on
Hi everyone,
I’ve had some issues where when turning on guides or grids or setting two
parallel rulers perpendicular to each other will cause the brush shape to
flicker. It will also follow the brush. I've attached some screenshots of the
flickering when the brush is static and when the brush is moving, for frames
where the flicker frame is on and off. I've attached a screenshot but there are
more on the thread I made on the krita-artists forum:
https://krita-artists.org/t/flickering-brush-when-using-rulers-or-guides/159635
The selected brush is an airbrush. However, the same glitch occurs no matter
which brush is selected.
Here’s a video of the flickering (Proton Drive link:
https://drive.proton.me/urls/80243NK1BR#agE0unKHLzoz).
Krita version: 5.2.14 (flatpak)
Operating System: Debian 13.2 XFCE
I did open up the 5.2.14 AppImage version of Krita and the problem isn’t there.
So whatever the issue is seems related to the flatpak version.
