On race, the black screen happens for half second as shown in the video. I use a hotkey to switch between workspaces.

This issue doesn't happen to me on default SRB2 Kart, SRB2, DRRR, etc.

Here's information that could be related maybe:
OS: Linux Mint 22.3, XFCE 4 Desktop Enviroment
Graphics card: EVGA GTX 650 1gb, Nvidia Driver 470.xx

EDIT: Timescale is increased to show the issue in a short timed video-

I assume this is with the games OpenGL renderer?
Tho im unable to repro this on either a KDE wayland session, nor running through xwayland or windows.
I asked @Indev450 to try and repro aswell on i3 so will wait for that.
If on OpenGL could you check if there happen to be any errors/warnings in "ogllog.txt" in the game folder right after this happens?

Yeah can't replicate on i3, so will have to see if there's anything on ogllog.txt

I forgot to mention that I'm using X11 and not wayland, idk if it's anything related.

Also sure

Hm yeah, seems like that got truncated again, should hopefully be fixed with https://github.com/Indev450/SRB2Kart-Saturn/commit/eccc3eb33fb280fd3dfa10e3a6ae5f22aacf25dd
I do have an idea what might cause this to happen, will make a branch later if you are up to test, otherwise i will set up mint with xfce test environment in a bit

Cant really think of anything else atm

Hmm that still appears to be truncated for some reason.
Anyways, sad this did not fix it so not quite exactly sure what might cause it.
I will probably set up a small mint with xfce test enviroment since rather not continue to shoot in the dark lol
and hopefully will be able to repro it there, but that might take some time since i need to make some space for it first.

I have a theory that could be XFCE specific. Saying this because I just decided to give a 2nd chance to Arch Linux with XFCE, and the problem still persists.

So I guess the Linux distribution doesn't matter. I'd have to try with another Desktop Environment.

Not sure why git just closed this by itself.
Finally had set up an xfce session and was able to replicate this issue.
Since Indev could not repro it in xfce this appears to be an issue within the Nvidia drivers specifically when keeping stencil testing enabled.
Since we dont need it for anything other than Portal render during level render, i just set it to disable stencil testing outside of that.
This has fixed the issue for me but would be great if you could also check if that resolved it for you! :)
