Created attachment 136826 [details] The artifacts SUMMARY When zooming in on an image and moving around, some persistent tearing artifacts will appear when moving diagonally. It happens with any image, both with mesa and nvidia. It doesn't occur with any other image viewer I've tried (not even KDE apps like KolourPaint and Okular). When changing the zoom level, the artifacts disappear. STEPS TO REPRODUCE 1. Open an image with Gwenview; 2. Zoom in; 3. Move the image diagonally. OBSERVED RESULT Tearing occurs. EXPECTED RESULT There should be no tearing. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.80.0 Qt Version: 5.15.2

Are you using a high DPI scale factor?
Yes, didn't think to mention that, but it seems to be the cause: I'm using a global scale of 150%, just tried switching to 100% and the tearing is gone.
Thought so. :) *** This bug has been marked as a duplicate of bug 417342 ***
Thanks for the quick response, Nate :) Hmmm, are you sure it's the same bug, though? I'm not seeing those grey lines; also, that was supposedly fixed on 20.12.2, but I've just compiled from git main and it still persists :(
Hmm, maybe it is different then.
I have got the same problem on Manjaro and I also use 150% scale factor in KDE Display Configuration KDE settings. If you need any info/logs from me, ask away. Operating System: Manjaro Linux KDE Plasma Version: 5.21.3 KDE Frameworks Version: 5.80.0 Qt Version: 5.15.2 Kernel Version: 5.11.10-1-MANJARO OS Type: 64-bit Graphics Platform: X11 Processors: 8 × Intel® Core™ i7-8705G CPU @ 3.10GHz Memory: 15,4 GiB of RAM Graphics Processor: Mesa Intel® HD Graphics 630
Have the same issue on 125% scaling. Starting from version 21.04.0 the bug partially fixed on Nvidia, but not on Intel.

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?
