Hi.

I do not have compositing enabled in xfwm4. I tried with it enabled
just to see and there is basically no change, only a slightly different
looking corruption which has some transparency through to the window
underneath rather than being completely solid.

With all Terminal instances verified closed and XLIB_SKIP_ARGB_VISUALS
set to 1 there is no real change in the corruption. I tried a couple
times just to be sure and on on one try it looked a bit different
than the previous screenshot:

Here are a few other screenshots of other applications where this is
occurring within Xfce:

I tested Terminal, Midori, and Claws in twm/Awesome earlier today and
they did not have corruption there, and it didn't happen in GTK+ 2.16 so
it doesn't *seem* to be video driver related (this is the radeon driver
in Xorg 7.4 by the way), but I could be wrong or missing something with
the differences in how those window managers may operate.

Thanks for the reply and info,
