Description Iain 2020-07-18 05:33:51 UTC

SUMMARY
After starting Kolourpaint for the first time, it's quick and responsive, but after using it for an hour it is noticeably slow to respond, this continues until you reach a point at which it's unusable. Shutting it down and starting again, makes no difference. The only solution is to restart my pc. Logging out and back in has no effect.

STEPS TO REPRODUCE
1. extended use, an hour is more than enough.
2. 
3. 

OBSERVED RESULT
Takes anything up to a minute to switch function, i.e. change from line drawing to circle drawing.

EXPECTED RESULT
Should switch function within seconds

when even this does not help, then it's not the fault of kolourpaint.

I assume you'll see the same problem with any other program (try with any other graphics program like gimp or krita, etc.)
I suggest to try a different graphics driver, since llvmpipe renders in software.
I'm no expert here but check https://docs.mesa3d.org/gallium/drivers/llvmpipe.html

Hi Martin,

Update on the program slowing down the longer I used Kolourpaint. I
uninstalled the Deb package & installed the more recent snap package, and I
am not experiencing the slow down, with the bonus, I have more options.

Iain ...
