Yes this bug still exists in Ubuntu 10.04 and Ubuntu 11.04. I have recently experimented with various X11 setups too. If I use the FrameBuffer driver (fbdev) the bug is gone. If I use the proprietary AMD/ATI Radeon driver the bug is gone. It seems only if I use the open source ATI (ati) or ATI Radeon (radeon) driver then the bug is there. So maybe that gives some clues as to where this bug is located?
