Shadowing the vim-window results in vim-gtk3 crash

[Vasilis]

With XFCE when I try to "shadow" the vim-gtk3 window (just to show only the title bar) it results in a vim crash and the window just disappears without any core dump neither .swp files on.
The only message I get on the terminal is

BadMatch (invalid parameter attributes)
Vim: Got X error
Vim: Finished.

This behaviour started from Xubuntu 18.04.
The vim-gtk package is not suffering from this problem.

Status changed to 'Confirmed' because the bug affects multiple users.

Still happens on xubuntu 20.04. Unfortunately, vim-gtk2 isn't around anymore, so the workaround is invalid.

[Vasilis (vasilis-vlachoudis)]

Indeed 20.04 still has the problem

This is apparently fixed upstream, but I haven't had a chance to verify.

The Groovy Gorilla has reached end of life, so this bug will not be fixed for that release
