Created attachment 173773 [details] Test RGB with artifacts SUMMARY Gwenview struggles with RGB PNGs reencoded by `zopflipng`, though other applications listed below don't have that problem. Black-White PNGs reencoded by `zopflipng` are not affected. In my case I created theese images in GIMP, but also achieved the same result with reencoding image created in Krita. Works under X11 and Wayland. STEPS TO REPRODUCE 1. Compress RGB PNG image through `zopflipng file.png` 2. Open it in Gwenview 3. Zoom it (Ctrl++, Ctrl+-, Ctrl+MouseWheel etc.) OBSERVED RESULT Random dots are shown, but ther are not included into picture directly. Firefox, Eye of GNOME (eog), Viewnior, gThumb and others are showing this image correctly, without theese dots, even if you'll zoom closely. EXPECTED RESULT I want it work as expected. SOFTWARE/OS VERSIONS Zopfli 1.0.3 (zopflipng is in this package) Operating System: EndeavourOS KDE Plasma Version: 6.1.5 KDE Frameworks Version: 6.5.0 Qt Version: 6.7.2 Kernel Version: 6.10.9-arch1-2 (64-bit) Graphics Platform: X11 ADDITIONAL INFORMATION Vanilla Gwenview, vanilla KDE Plasma, vanilla EndeavourOS.
