--- Comment #8 from Rebecca Breu <rebe...@rbreu.de> ---
Ah, sorry, I cut off the copy&paste. At the end is the whole system info.
Playing around with the settings, I found out:
When I remove my kritarc and kritadisplayrc, the rendering issue almost doesn't
occur at all. Out of at least 50 tries, probably more, I had it happen twice.
(So maybe the Krita versions I listed in my initial report as "working" for me
also just have this issue super rarely instead of not at all? I always loaded
several times, but not THAT often.)
Unfortunately, during testing I accidentally overwrote my config files as of
yesterday, but with an older version, I get the rendering issue as well, but
only sometimes. It can go well for 20 times or more, and then fail for 20
times. I can't find anything that influences it. This is the kritadisplayrc:
[General]
EnableHiDPI=false
EnableSingleApplication=true
LogUsage=true
OpenGLRenderer=auto
canvasState=OPENGL_SUCCESS
rootSurfaceFormat=bt709-g22
And the according Current Settings:
Current Swap Location: /tmp
Undo Enabled: 1
Undo Stack Limit: 100
Use OpenGL: 1
Use OpenGL Texture Buffer: 1
Use AMD Vectorization Workaround: 0
Canvas State: OPENGL_SUCCESS
Autosave Interval: 300
Use Backup Files: 1
Number of Backups Kept: 1
Backup File Suffix: ~
Backup Location: Same Folder as the File
Use Win8 Pointer Input: 0
Use RightMiddleTabletButton Workaround: 0
Levels of Detail Enabled: 1
Use Zip64: 0
Once I have access to my backup, I can retrieve the latest Krita configs. Not
today though.
