I can't reproduce this on my end using arch packaged mangohud and glfw

Did you try wayland?

This should work fine inside gamescope, which mangoapp is designed to be run inside of. Any error caused or only happens outside gamescope is non issues basically

Actually I use mangoapp inside gamescope(https://github.com/ChimeraOS/gamescope-session), and it will also crash on glfw 3.4.

in the example you showed you were not using gamescope, can you show with gamescope?

It is the same as the first screenshot. Glfw Error 65550: X11: Platform not initialized for 4 lines. And the mangohud did not show inside gamescope with steamdeck mode steam. And nothing changed after tweaking mangohud config in steam(steamdeck mode)'s sidemenu. But after downgrade to glfw-x11 3.3.10, everything work again.

I don't see any issues on my end using latest mangohud git and glfw 3.4 on x11 and @gort818 also tested the same on wayland using gamescope -- sh -c "mangoapp& vkcube" as test case

I am having the same issue. gamescope -- sh -c "mangoapp& vkcube" runs fine but mangohud is not launching on wayland or gamescope with steam using a similar script to the chimeraos session above.

The crash happens when attempting to create the atom after a failed initialization. For some reason, the initialization does not return false.

Downgrading to glfw-x11 3.3.10 fixes the issue.
