Symptoms

Having the game in focus causes the problem. The issue presents itself in full screen and windowed full screen mode. When I start the game up it'll freeze at the unity logo. However when I'm alt tabbed it'll load just fine until I tab back into the game. I've been able to get around this issue by starting up a video in Firefox and using the picture in picture feature. This workaround will solve the issue with any window that you can set to "always on top" in the WM. It works perfectly fine once I have some other window open on top of the game. Playing the game in windowed mode also solves this issue, however getting to the settings menu for someone opening the game for the first time would be difficult due to the issue.

Reproduction

1. Start the game.
2. At the first loading screen the game will freeze, this will cause the x session to lag until tabbed away or pressing the super key to go to the gnome overview.

Reproduction of solution

1. Open any window in gnome that supports right clicking on the window and selecting "Always on Top" and enable the option
2. Start the game

Compatibility Report

• Name of the game with compatibility issues: Lethal Company
• Steam AppID of the game: 1966720

System Information

• GPU: NVIDIA GeForce RTX 3070 Lite Hash Rate
• Video driver version: nvidia-dkms 545.29.06
• Kernel version: 6.6.10-273-tkg-eevdf
• Link to full system information report as Gist:

I confirm:

• [x] that I haven't found an existing compatibility report for this game (at least, not with this particular usage scenario)
• [x] that I have checked whether there are updates for my system available.

Symptoms

The game runs just fine without the VR mod, but with it, like with some other Unity OpenXR-based games and mods, the game will not run. Specifically, I get a few frames of the "Made with Unity" startup screen showing in my headset, and then the headset crashes with error (-203) and the game freezes and must be force-exited.

Reproduction

Start up SteamVR and Index knuckle controllers, and attempt to launch Lethal Company modded through r2modman with only the LCVR mod and its one dependency active.

I can't send logs as they weigh 500MB, here is a line that is repeated a million times: 0:00:01:01.451814886 80141 0x7a07601072c0 ERROR WINE unixlib.c:246:push_event: Failed to push eos event 0x7a0738001c70 to pad src.

1. Going into the game.
2. Create a lobby.
3. I wait for about 15-20 seconds and the game hangs completely.
