Instant crash when opening fullscreen apps

[seacat17]

Describe the bug
The server instantly crashes the moment I try to open any fullscreen program on it. I am trying to open a game to have a workaround for an issue with DXVK.

To Reproduce
Steps to reproduce the behavior:

1. Launch TigerVNC server;
2. Connect to the server, you can use any settings;
3. Open any fullscreen app on it. In my case it's VotV launched with PortProton;
4. The server immediately crashes.

Expected behavior
Shouldn't it just display what Xorg is displaying? Or does it not like switching between display modes this much?

Screenshots

Client (please complete the following information):

• OS: Arch Linux x86_64 (6.13.2-arch1-1);
• VNC client: TigerVNC;
• VNC client version: 1.15.0;
• Client downloaded from: Arch Linux repo.

Server (please complete the following information):

• OS: Arch Linux x86_64 (6.13.2-arch1-1)
• VNC server: TigerVNC
• VNC server version: Cannot check, I assume that it is the latest one;
• Server downloaded from: Arch Linux repo.
• Server was started using: "vncserver :1" with config file in /.config/tigervnc/

Additional context
Both the client and the server are on the same computer. I have an issue with DXVK that makes me launch another Xorg server on tty2 to play certain games. I am trying to make this less unpleasant by allowing myself to contain the game on my taskbar within the VNC viewer.

Thanks for your report.

These crashes have so far been bugs in the GPU drivers. What GPU(s) do you have in this system? vulkaninfo --summary should give you an overview.

Thank you. I'm afraid this is a known bug in the AMD driver. Please see #1772.
