Minecraft: 1.20.1
Fabric Loader: 0.16.5
Fabric API: 0.92.2
ImmersiveAircraft: 1.1.2
Amecs: 1.3.10

Whenever I close any interface ingame the live log gives 8 of this error:

:########## GL ERROR ##########
:@ Render
:65539: Invalid key -1

This occurs when these are binded to something

Backward
Down
Forward
Left
Pull controller
Push controller
Right
Up

Does it cause issues tho? OpenGL likes to yap a lot, but it does not always cause problems.

It works fine. No gameplay issue.

Then I will close this as intended, using -1 to indicate an unassigned key is afaik the intended way and I'm not aware of a workaround.
