Ubuntu 20.04 - AMDGPU - VDPAU - Loop - X11 Error BadIDChoice

[Rich Johnson]

Summary of the bug:
OS: Ubuntu 20.04 (server building running nodm & matchbox-window-manager)
MPlayer Version: Latest (Sep. 20, 2021) SVN Build (also happens with 1.4)
Hardware: AMD Ryzen 3 3300U w/ Radeon Vega Mobile Gfx

After a couple of hours of looping the same exact file, Big Buck Bunny for example, MPlayer freezes with the following 2 lines of error message:

X11 error: BadIDChoice (invalid resource ID chosen for this connection
X11 error: 140

I have tested both MPV & VLC with the same VDPAU drivers & Codecs and it either doesn't occur, or hasn't occurred yet, but those ran for the past week in testing just fine.

How to reproduce:

Patches should be submitted to the mplayer-dev-eng mailing list and not this bug tracker.

This bug reports seems relevant.

Unfortunately I couldn't reproduce the error.

Can you still reproduce this?

[Rich Johnson]

Yes, it is still reproducible on 20.04. I haven't tried on 22.04 yet.
