Bug 495056

SUMMARY
When enabling "Sync playback to display" in Kodi (Settings -> Player), Kodi crashes immediately when trying to play a video, with a division by zero exception.

STEPS TO REPRODUCE
1. Log in to a Plasma Wayland session
2. Run Kodi (either a local installation, Snap or Flatpak)
3. Go into settings -> Player and make sure "Sync playback to display" is on (this may require changing the "settings mode" to "Standard" or higher).
4. Go to the main view and try to play a video from Kodi's library (you may need to add a video source to some place where there are playable videos).

OBSERVED RESULT
Kodi immediately crashes

EXPECTED RESULT
The video should play

ADDITIONAL INFORMATION
According to the discussion in the open Kodi issue here - https://github.com/xbmc/xbmc/issues/25850 - the problem is that kwin_wayland does not send the `sync_output` event before calling the `presented` presentation feedback event. From a quick review of the code - I don't think kwin_wayland ever calls `sync_output` - which Kodi relies upon to detect the refresh rate of the display it is playing on. According to the developer - other compositors are doing this "correctly".
