Hey, I just ran into this issue today.
What solved it for me was running:
"SDL_VIDEODRIVER=wayland ./ut-bin-arm64"
From within "~/.local/share/OldUnreal/UnrealTournament/SystemARM64"
I am also on a 500+ with Trixie.
BTW there is also now an OldUnreal patch for UT2004 Linux that has an ARM binary with it, but I am currently running into it crashing with:
"Can't find file 'Entry'" which is the opening scene under the Maps dir. So I think this may be a bug with the UT2004 patch.
