I understand this is an exceptionally minute edge-case, and don't expect to see any fixes as a result, but until recently when I hosted events, I would run a VO client through WSL. The fact that VO could even run at all, let alone as well as it did, was quite astounding.

Why? Well, because the launcher uses a registry value to determine where your game is located instead of the location of the launcher's executable, splitting settings was a bit annoying. While I run my normal client with max settings and full resolution, I want Event Camera to be using minimal settings in a tiny window on my other monitor. I also want completely seperate plugins to be utilized by each client. Since at the time I didn't have a laptop, my eventual conclusion was to get VO running in WSL, which was admittedly very pain free.

I'm assuming the latest update's change to using X RandR killed VO's ability to run through WSL, however. The instant the game is launched, the error reporter shows up. I'll dump my errors.log in the next post.

I can just use my laptop to get the same result now, so i'm not too torn up, but figured i'll report anyways.

Have you looked into the libGLU issue? This seems like it's probably related.

Progress - it finds the reference driver now! Still immediately crashes, now during instantiation.

Try adding xrandr=0 to your [gl4] or [refgl] config.ini settings (whichever one you're trying to use, or add it to both).
That will bypass the use of the X RandR extension, so we can see if that's the cause of your problem.

with this bypass, the game launches just fine once again! You've resurrected it, Ray, thanks~

I also had this problem. adding xrandr=0 to the [gl4] section fixed it.

A client patch has been released to fix this problem.
