[Pkg-xfce-devel] Bug#473347: xfwm4: Redraw bugs when switching workspaces with overlapping sticky windows

[Dylan Thurston]

Package: xfwm4
Version: 4.4.2-2
Severity: normal

If I have a sticky window, A, (on all workspaces), and switch to a
desktop with another non-sticky window, B, beneath it, frequently the
contents of window B are incorrectly drawn.  Example attached.  The
window in the center is sticky and is above the other window in the
list.  'xfwm-bug1' is taken in a workspace with only that window in
the given region; 'xfwm-bug2' is taken after switching workspaces.

In both cases I have other open windows on my desktop, not shown.  In
case it's relevant, I'm using a dual-head setup.

I haven't figured out the entire necessary conditions, but it happens
very frequently and is easy to reproduce.
