The vacuum cleaner. One cat gets really scared and freezes while the other starts hissing at the machine when I bring it out.

My guess is that it should infinitely call echo on itself where the $() substitutes the command echo into the terminal, which calls it with echo.

I get the same errors about descriptor, but no mention of mlt or missing libraries.
I tried the flatpak version and that seems to be working.

There should be a config file in ~/.config/MangoHud (you can check more details in the GitHub page https://github.com/flightlessmango/MangoHud#hud-configuration).

By adding frametime=0 to the config file, you should be able to remove the frametime measurement from the FPS display.
