More problems. Sometime the popmenu on gtk app doesn’t show. And it has errors in weston.log.

Expected behavior

Actual behavior

Window doesn’t render sometimes. It does after killing it and restarting it after a while.

I was just able to get apps working again without needing to shutdown wsl by remounting /mnt/shared_memory in the system container:

 wsl --system umount /mnt/shared_memory '&&' mount -t virtiofs wslg /mnt/shared_memory -o dax

umount wasn’t able to unmount shared_memory until I’d closed all the Linux app windows, but this got things working again.

Update: this appears to have put WSLg into RAIL mode instead of VAIL, identified by [WARN: COPY MODE] in the taskbar tooltips, but I was able to resolve that by killing both Weston and msrdc.exe.

Encountered similar issue, after going away for a while came back to hung gui window and errors in the weston.log:

Killing the application and starting again instantly crashed it/didnt start the window, but the process itself didn’t exit:

The GUID changes every time the application is started unsuccessfully.

After doing wsl --terminate Debian wslg didn’t even start and only had stderr.log:

<3>WSLGd: Exception: Input/output error @../main.cpp:144 (main)

After wsl --shutdown it started working again (I had docker images running, but didn’t try to kill just those before --shutdown).

@ThaDaVos I didn’t try yet but you can enable WESTON_RDPRAIL_SHELL_ALLOW_ZAP which restarts weston compositor and Xwayland by pressing Left-Ctrl + Left-Alt + Backspace.
