Package: xwayland
Version: 2:1.20.0-2
Severity: normal
Tags: patch
Dear Maintainer,
while trying to watch the German TV show "Die Sendung mit der Maus" from
https://www.wdrmaus.de/aktuelle-sendung/, my Gnome desktop freezes. I can
SSH into the machine and see that Xwayland eats 100% CPU. The freeze can be
reproduced, it happened every time I accessed the above URL in Firefox 60.
I found a similar issue in the Red Hat bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1579067
The issue mentions patches in
https://patchwork.freedesktop.org/series/43618/. I applied them to the
xorg-server source, built and installed the package and the freeze does not
happen anymore.
The patches are also attached to this bugreport.
Regards,
Tino
