Black screen on some games

[Altair-85]

Device: Raspberry Pi 4B & Raspberry Pi 5
OS: Raspberry OS Bookworm (ARM64)

I can easily install and launch RMG from Flathub. Games start with sound only & black screen.
Same Problem for Orange Pi 5 Plus with Ubuntu 24.04 (ARM64).

You have to force an OpenGL override to 3.3, I don't know how to do it for the raspberry pi but for my pinebook pro the environment variable is MESA_GL_VERSION_OVERRIDE=3.3 which makes it work.

Thanks for the quick reply. Sorry do you have a tutorial for me on how to do this? I'm new to Linux.

Can you try v0.6.5? it should work out of the box

I don't want to open new issue yet since this may be related to parallel, but @Rosalie241 please have a look at
Themaister/parallel-rdp#69 , on whether this have to do with RMG or not.
EDIT: Simple64 seem not to have this issue.
