[Nicholas Shatokhin (robotex)]

Hm, see the top's output in gedit's window. It is the moment when I drag gedit's window with pressed alt.

[Daniel van Vugt (vanvugt)]

Nicholas, could you please check to see if a window-decorator process is running?

Just open a terminal window and run:
 ps x | grep window-decor

What does it show?

[Nicholas Shatokhin (robotex)]

It's repairing after reboot or logout. So, I will can see this only when I will see this bug again.

[Sebastien Bacher (seb128)]

could you add your .xsession-errors to the bug if it happens again?

[Michal Hruby (mhr3)]

Got this as well, gtk-window-decorator crashed, apport poped-up, but it doesn't want to upload it itself, so here's the stacktrace

[Sebastien Bacher (seb128)]

that seems like bug #754649?

[Sebastien Bacher (seb128)]

bug #980309 as well if you want a recent one

[Eleni Maria Stea (hikiko)]

This bug is old and cannot be reproduced atm, so I marked it as Won't Fix. If you still experience the problem feel free to re-open the bug. Thank you!
