I see this too (edgy) and it's infuriating. Another way to trigger it is to switch between virtual desktops when another window is present on the desktop you're switching *from*, that occupies the same space as rdesktop on the desktop you're switching to.
However I suspect the problem is deeper than rdesktop: A couple of times now I've seen it happen with gaim too. I wonder if it's a metacity, x server or video driver issue that rdesktop just exacerbates more than other programs. -- Cosmetic (but annoying) redraw issues https://launchpad.net/bugs/18613 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
