Video decoding stops working after a while

_JCM_

I am using Ubuntu Touch 24.04-1.0 (Release candidate channel) on my Fairphone 5 (Android 13 kernel as recommended) and video decoding stops working after the device has been powered on for multiple hours.
Once that happens, no app that uses hardware decoding is able to play videos (e.g. Media Player, Morph Browser and even Android apps in Waydroid).

Trying to play a video in Media Player results in an "Error playing video" popup with the message "Failure connecting with playback backend." and the following journal messages:

Rebooting the phone fixes the issue; however, it is quite annoying having to reboot so frequently.

Has anyone else experienced similar issues or knows how to fix this without a full reboot?

@_JCM_ Sadly this is an issue even on focal. It also happens on other devices although I notice that it is more frequent on my FP5 than my other devices like FP4.

99% certain this has something to do with waydroid. I get it all the time on fp4, but only after i used waydroid. Is there an open issue somewhere on gitlab?
