Linux Desktop and HTPC client (flatpak) only black screen

Player Version#: Plex desktop flatpak ver 1.56.2.

I’ve installed the flatpak plex desktop client on a freshly installed fedora 36.
After launching the app I only can see a black screen.
The console outputs:

$flatpak run tv.plex.PlexDesktop
Cannot load libcuda.so.1
[57:64:1106/173836.223376:ERROR:command_buffer_proxy_impl.cc(141)] ContextResult::kTransientFailure: Failed to send GpuChannelMsg_CreateCommandBuffer.
[5:5:1106/173836.597879:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted
[5:5:1106/173836.603579:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted
[5:5:1106/173837.338878:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted

A similar thing happens when I try to start the latest Plex-HTPC flatpak image:

$ flatpak run tv.plex.PlexHTPC 
Cannot load libcuda.so.1
[5:5:1106/172805.840274:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted
[5:5:1106/172805.844978:ERROR:context_group.cc(146)] ContextResult::kFatalFailure: WebGL1 blocklisted

I am grateful for any help!
You can find both log files in the appendix.

Plex HTPC.log (153.2 KB)
Plex.log (86.5 KB)

Try DISABLE_WAYLAND=1 flatpak run tv.plex.PlexDesktop and see if that makes a difference. If so, the next version should resolve this.

I’ve tried this as well, but no difference at all.
