When playing a video fullscreen using mpv, a lot instances of the following warning appear in the journal: > kwin_wayland[1182]: kwin_wayland_drm: Page flip failed: Invalid argument The frequency of warnings correlates with the video frame rate. (This can easily be observed by changing the playback speed using {, [, ], or }.) The maximum warning frequency seems to be the refresh rate of the monitor where the video is shown. When playing fullscreen videos on several monitors, the warning frequencies add up. In the worst case, I get 135 warnings per second when playing a video fullscreen on a 60Hz monitor in parallel to a video fullscreen on a 75Hz monitor. (“sort | uniq -c” helps determining the warning frequency.) Besides the warnings I do not notice any problems. The problem does not occur when not in fullscreen mode. Also, I cannot cannot reproduce the problem with VLC, MPlayer and Dragon Player.
