How to fix the video problem on Wayland

Some people reported problems when using SMPlayer on a Linux desktop with Wayland. The main problem usually is the video being on a separate window, but it can also be a black window or a crash when trying to play a video.

Here is how to fix it. There are two possible ways:

  1. Select a different video output in Preferences -> General -> Video. Usually at least x11 should work.
  2. Install SMPlayer using a flatpak or snap package. These packages provide patched versions of mpv and mplayer which should fix the problem. More info here: https://www.smplayer.info/install-snap-flatpak-appimage.php
