Pictures are also shown correctly. Video playback works as expected in Wayland session. STEPS TO REPRODUCE 1. Open Gwenview from within X11 session 2. Select any supported video file for playback OBSERVED RESULT Black screen (background color) where video should be visible, audio works EXPECTED RESULT Video and audio should be working.

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? If yes, are you sure that it is not a dependency issue (sounds like a classic ffmpeg problem).
