gdk_monitor_get_geometry: assertion 'GDK_IS_MONITOR (monitor)' failed

[Tealk]

Overview Description:

When I try to play a .mp4 video with H.265 Codec, I get the following error message:

In the terminal I see the following message every time I start the programme, whether flatpak or rpm:

Cannot load libcuda.so.1

(io.github.celluloid_player.Celluloid:7584): Gdk-CRITICAL **: 09:47:22.267: gdk_monitor_get_geometry: assertion 'GDK_IS_MONITOR (monitor)' failed

I noticed it because I wanted to use the Flatpak to avoid the codec problem of Fedore Silverblue.

Steps to Reproduce:

1. start celluloid

Version: 0.26

It turned out this error was caused by the Fedora flatpak, which lacks support for H.264/H.265 decoding. The Flathub version works correctly. And the RPM package lacks H.264/H.265 decoding support by design, so this is expected behaviour.
