[Linux] [GDLauncher] Loading screen is black, main menu does not appear

[hron84]

I cannot launch a single game because the main screen is blacked out even after I guess it finished loading.

I tried to disable the CustomMainMenu mod, it makes the MOJANG logo appear but the main menu / game creating looks like this (attached screenshots)

I try to run the instance under GDLauncher on Arch Linux with an nVidia GPU and native nVidia driver. There is no error in the log other than a periodically repeating

[22:04:07] [Client thread/ERROR]: DRAGONAPI ERROR: GL ERROR 1281: FB #0 was unrecognized (status=36053)
[22:04:07] [Client thread/INFO]: DRAGONAPI: This should be impossible! Driver issues?

... after loading the game.
