SUMMARY

When using fractional scaling (125%) the default paintbrush tool, eraser, and color eraser, leave trail behind as you move the cursor within the canvas. It seems to happen with 'custom' Kolourpaint cursors.

STEPS TO REPRODUCE
1. Set fractional scaling
2. Open Kolourpaint
3. Start moving the cursor within the canvas

OBSERVED RESULT

Cursor leaves weird trail behind

EXPECTED RESULT

Cursor doesn't leave trail
