krita thinking hard for a long time
SUMMARY
when i use any rotation method using the pen for control, i get huge lag
issues,freezing, but not crashing krita.
this is probably the fault of my old hardware, but rotating using the "rotate
canvas left/right" commands works well, so there might be a way to improve the
other rotation methods too...
STEPS TO REPRODUCE
- 500x500px single layer image
1. shift + space + lmb to rotate
2. rotating using the slider in the pop up pallette
3. shift + alt + space + lmb to rotate
OBSERVED RESULT
-freezes, ranging from 20 seconds to over 2 minutes (thermal throttling
probably), no crashes.
-one of my two cpu cores at 100%, the other one is idle
-ram use normal, with 1.5gb left
