AMD GPU: GUI is rendered incorrectly all over the window

Hey,
I had to switch to a new computer and while the simulations are running as always, I can't use the simulate.exe anymore.
The GUI is rendered all over the place (see screenshot). The buttons are still clickable on the left black panel, although not visible.

The PC:
ASRock X670E Pro RS
AMD Ryzen 5 7600X (with integrated graphics)
32GB RAM
M.2 SSD
AMD Radeon RX 6800 XT
Windows 11 22H2 (22621.819)

I've tried the latest AMD Adrenalin (22.5.1 and 22.11.1) and PRO (22Q4) graphics driver versions.
I've tried different mujoco releases (2.3.0, 2.3.1) and built it from the source code, always with the same result.
Any help is appreciated.
