held_keys["<any key>"] does not release on Ubuntu 24.04

[stonier]

Environment

• Ubuntu 24.04 fails (we tested on multiple machines)
• Ubuntu 20.04 succeeds

Reproduce

• Run the Introduction Tutorial verbatim on Ubuntu 24.04.
• Press 'd' and release - the box moves continuously across the screen
• Press 'a' and release - the box stops

If printing the values of held_keys["a"] and held_keys["d"] they get set to 1 but never return to 0 on releasing.

Expected Behavior

The box stops moving after d is released.

Other Notes

Seems like something has changed under the hood with the graphical server in-between Ubuntu releases.
