Created attachment 154097 [details] The content is scaled even if Kolourpaint is at 100% The content in Kolourpaint should NOT be scaled with DPI setting STEPS TO REPRODUCE 1. set global DPI scale to 125% 2. paste any screenshot in Kolourpaint OBSERVED RESULT The content will be scaled even if Kolourpaint is at 100% EXPECTED RESULT The content in Kolourpaint should NOT be scaled, just like what the graph shows in Gwenview at 100% SOFTWARE/OS VERSIONS Linux/KDE Plasma: Arch Linux 6.0.10 KDE Plasma Version: 5.26.3 KDE Frameworks Version: 5.100.0 Qt Version: 5.15.7 ADDITIONAL INFORMATION
Created attachment 166931 [details] KolourPaint at 150% display scale This problem still persists after upgrading to KDE 6. Scaling makes most applications look better, but graphics applications like KolourPaint should not scale the image it is editing. I added a screenshot. I set the "Scale" in "Display & Monitor" in "System Settings" to 150%. I confirmed that KRuler measures the actual number of pixels on the screen (my screen is 2560x1600). I set the image size of the content in KolourPaint to 640x480, and KRuler shows that it is actually 960 pixels wide on the screen. This behaviour is problematic. For example, I can no longer draw a sharp one-pixel line. I can't inspect any given image in a pixel-accurate way as it will always be scaled.
