Created attachment 135877 [details] Screenshot of Gwenview's broken graphics. Under Wayland, Gwenview does not render any images correctly. STEPS TO REPRODUCE 1. Log in with a wayland session 2. Open any image file with your usual file browser (in my case, Dolphin), or from within Gwenview's own file browser. OBSERVED RESULT Application window opens with corrupted graphics where the image is supposed to show up. EXPECTED RESULT Application window displays requested image. SOFTWARE/OS VERSIONS Operating System: KDE neon 5.21 KDE Plasma Version: 5.21.0 KDE Frameworks Version: 5.79.0 Qt Version: 5.15.2 Kernel Version: 5.4.0-65-generic OS Type: 64-bit Graphics Platform: Wayland Hardware Processors: 12 × AMD Ryzen 5 3600 6-Core Processor Memory: 31,4 GiB of RAM Graphics Processor: Radeon RX Vega 56 Additional information: Gwenview displays any image I have normally under an X11 session, and Gwenview's own file browser shows thumbnails of the images, but fails to display them when it tries to open them for a full-size view.
I can reproduce this if I change Animations to 'OpenGL' (Settings > Image View). If I use 'Software', images render as usual. Can you confirm what your system is using?
