Description Laura David Hurka 2021-08-21 10:38:02 UTC 
SUMMARY
When used on a hiDPI screen, images are displayed bigger than they should.

The checkered background is zoomed to e. g. “Fit” or “Fill”, but the image on top is
1. displayed too large, so it exceeds the checkered background at the bottom-right,
2. blocky.

Only SVG images seem to be affected.

STEPS TO REPRODUCE
1. Turn the screen scale above 100%
2. Open e. g. an SVG icon (which has transparent portions)

OBSERVED RESULT
The rendered image is blocky and exceeds the checkered background, and probably even the largest possible viewport.

EXPECTED RESULT
The rendered image is not blocky and has the requested size.

SOFTWARE/OS VERSIONS
Operating System: KDE neon 5.22

Can reproduce when the "Enlarge smaller images" setting is active.

I can not notice a difference when this setting is enabled or disabled. Just 
the initial zoom is different, which can be undone with the zoom slider.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0 (the latest released version)?
