I'm using X11 (not Wayland)The issue happens on Wayland. On X11 the RetroArch menu works (although some of the menu icons are black squares and a few other glitches).
If the 1.9.0 you tested was the flatpak, I wonder whether it's possible for you to also to test a flatpak of 1.7.3, in case there is a relevant difference in the build environment or the libraries used?
The oldest available version of RetroArch on Flathub is 1.7.6: $ flatpak update --commit=a437b0ef4eb1f1563d84a8ec881b9f19eb9fb84c06b35ecafe4ce85d5aad918a org.libretro.RetroArchThat version does have the menu freeze issue under Wayland which I guess means that the issue has been fixed in upstream.
Could you please run it as "retroarch --verbose" and post some or all of the output up to the point where it freezes?
