I have an Nvidia GPU so Wayland is very unstable for me, lots of flickering and windows turning to black rectangles. Playback was bad for me too with Haruna. VLC played it smoothly, mpv only gave me a black window with audio and SMPlayer wouldn't open the file at all. So I couldn't compare with another mpv based player. Setting the scaling back to 100% improved playback a little. The above is for my 2560x1440 screen, on my 1920x1080 it was better, but still choppy. I have been testing this on an older and lower end PC and it doesn't look like something I can solve. Here's a bug on mpv's issue tracker I opened on the subject, but so far got no response https://github.com/mpv-player/mpv/issues/9417 I also asked on kde mailing list, but got nothing helpful. Hmm, after taking a look at the VLC comment https://github.com/mpv-player/mpv/issues/9417#issuecomment-963132782 it seemed to me like it might be a Qt issue, and I found this: Suboptimal playback performance with 4K@60fps when using QML MediaPlayer + VAAPI HW decoding https://bugreports.qt.io/browse/QTBUG-79301 , closed without any comments. It's awfully similar, but I'm not sure it's relevant, Haruna doesn't seem to use QtMultimedia/MediaPlayer. Try with the latest changes. If you can't compile it yourself use the flatpak from the kde remote https://userbase.kde.org/Tutorials/Flatpak#Nightly_KDE_Apps |
