Public bug reported:
After some uptime, xfwm4 is VERY slow at something, to the point that
it's consuming 100% of CPU on a Xeon system and making the system
entirely unusable. I don't know who is leaking what, but somebody is
clearly leaking something.
I don't have debug symbols, so this is the best I can get:
