Created attachment 137876 [details] Screenshots of KolourPaint. 100% zoom and 80% zoom. SUMMARY Main canvas on kde with fractional global scale. 100% canvas scale is not really pixel-perfect when global scale in display settings is 125%. It becomes pixel perfect only when you set 1/1.25=80% zoom. STEPS TO REPRODUCE 1. System Settings -> Display and Monitor -> Display Configuration -> Global Scale to 125%. 2. Open KolourPaint and draw some random things with it. 3. Set 100% zoom and see that it is not pixel perfect. 4. Set 80% zoom and see that it is pixel perfect. OBSERVED RESULT In "STEPS TO REPRODUCE" EXPECTED RESULT Set 100% zoom and see that it is pixel perfect on any global scale.
