Created attachment 151014 [details] aliasing present at "100%" zoom SUMMARY When viewing an image, dragging the zoom slider to 100% shows artifacts. However, if you set the zoom to the 100% preset, it shows the pixel-perfect image. I have added a checkerboard from here https://images.alphacoders.com/951/thumb-1920-951489.png for best viewing of the bug. STEPS TO REPRODUCE 1. Open the checkerboard image 2. Attempt to drag the slider to 100% 3. If you just miss it an end up at 99% or 102%, resize the window a little 4. Drag the slider back to the left and try dragging it to 100% again 5. Repeat 3-4 until you land on 100% OBSERVED RESULT Rectangle edges are jagged and aliasing despite the image supposedly being at 100% zoom. EXPECTED RESULT I suspect it isn't actually rounding the zoom value to the nearest integer, just rounding the displayed amount. 100% should accurately reflect the preset value of 100%.

I could not reproduce this on gwenview 22.12.0
Reproduced again with Gwenview 22.12.3 following the provided instructions. Manually selecting 100% immediately corrects the image's aliasing.
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)?
