Bug ID: 449550
Summary: Checkered pattern on Filter Layers that are

Product: krita
Version: 5.0.2

OS: Linux
Status: REPORTED
Severity: major

Screenshot of the bug.
SUMMARY
***
When creating a Filter Layer, like Color Balance or Levels, and then changing
that Filter Layer's opacity from 100% to 75% (for example), an ugly grid
appears. This grid isn't apparent when the Filter Layer is set to 100% opacity.
The grid's intensity multiples with the number of Filter Layers you have (if
those Filter Layers are also set to an opacity level below 100%).
This problem doesn't exist on Android or Windows but I've been able to recreate
it with everything I've worked on in Manjaro Linux using Krita 5.0.2 from the
official repositories as well as the app image and the flatpak variants.
STEPS TO REPRODUCE
1. Create a Color Balance Filter Layer and adjust the values.
2. Reduce the Filter Layer's opacity from 100% to 50%
3. That should do it.

-Opening my files in Android and Windows (where the grid problem is not
present).
