metacity-3.44.0-1.fc36 crashes inside x2go session
metacity --replace
(metacity:60152): metacity-WARNING **: 21:19:54.390: Failed to create compositor: Missing composite extension required for compositing
(metacity:60152): Gdk-WARNING **: 21:19:54.513: The program 'metacity' received an X Window System error.
This probably reflects a bug in the program.
The error was 'BadRequest (invalid request code or no such operation)'.
(Details: serial 1518 error_code 1 request_code 148 (X-Resource) minor_code 4)
(Note to programmers: normally, X errors are reported asynchronously;
that is, you will receive the error a while after causing it.
To debug your program, run it with the GDK_SYNCHRONIZE environment
variable to change this behavior. You can then get a meaningful
backtrace from your debugger if you break on the gdk_x_error() function.)
Well, normally i don't use metacity, it was only a test for fixing libwnck in a x2go session with MATE Desktop. libwnck#154 I suggest to reproduce the issue by yourself. Connecting to a qemu VM via x2go is very easy. See https://www.addictivetips.com/ubuntu-linux-tips/set-up-x2go-on-linux/
