Bug ID: 472707
Summary: Fractional scaling under gwenview / wayland not
correct
Classification: Applications
Product: gwenview
Version: 23.04.3
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: gwenview-bugs-n...@kde.org
Reporter: pixelplanet...@gmail.com
Target Milestone: ---
SUMMARY
Even thought that i set global scaling to 150%, i expect a 4k image, displayed
on a 4k screen, to be as large as the screen when it's at 100% zoom within
gwenview.
I don't expect the image to be up- or downscaled.
This is not the case in gwenview.
STEPS TO REPRODUCE
1. use wayland on a 4k monitor
2. set scale to 150% (in screen settings)
2. make fullscreen screenshot (screenshot correctly has 4k resolution)
3. watch the screenshot with gwenview at 100% scale (in gwenview)
OBSERVED RESULT
Screenshot is scaled to 66%.
If i set gwenview to 150%, i get the correct size but blur from scaling.
EXPECTED RESULT
No weird scaling, no blur.
1px at the screenshot -> 1px at the screen
