Environment

Windows build number: Microsoft Windows NT 10.0.22000.0
Your Distribution version: 20.04
Your WSLg version: 1.0.26

Steps to reproduce

• Run a ressource heavy GUI application (such as running an Ubuntu VM in virt-manager)
• Try to use the GUI application and wait for it to crash

WSL logs:

• Attach WSLg logs from /mnt/wslg

You can access the wslg logs using explorer at: \\wsl$\<Distro-Name>\mnt\wslg (e.g.: \\wsl$\Ubuntu-20.04\mnt\wslg)

• pulseaudio.log
• weston.log
• versions.txt
• stderr.log
