[Pkg-xfce-devel] Bug#443873: xfwm4: switching virtual desktops makes windows flicker

[Meelis Roos]

Subject: xfwm4: switching virtual desktops makes windows flicker
Package: xfwm4
Version: 4.4.1-3
Severity: normal

*** Please type your report below this line ***

Since last xfce upgrade (previous was around the end of July), virtual desktop switching is 
flickering. I have 4 desktops with xfce-terminals, seen in pager too. Ctrl-F1..Ctrl-F4 switch 
between these. With latest xfce, swithcing to another desktop makes the new window appear, 
then flicker to something (else?) and then reappear. This makes desktop switching slow and 
unpleasant.

It has also happened 2-3 times that after trying to switch to another screen, it keeps 
flickering between 2 or 3 desktops and does not stop for quite many seconds. I tried pressing 
Ctrl-F* again and the flickering did not stop at once, but did several more seconds later 
(maybe because of the switch, maybe not). I can not reproduce this at will.

Pentium 3, 600 MHz, 320M RAM (old IBM X20).
