Comment 3 for bug 901959

Forwarding this bug from Ubuntu (sounds like it affects Fedora too):
http://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/901959

When launching LibreOffice, a welcome panel is displayed. On Intel video drivers the left and right edges of this window are unpainted. See attached screenshot.

I reproduced the bug on Ubuntu Precise (12.04) by running `libreoffice` from a terminal window.

Michael Stahl (RedHat) originally found this issue (found in Fedora 16), and did some further analysis:

< mst_> we set up a clipping region with XSetRegion that has 4 rects
< mst_> then we paint about 40 polygons for the gradient, covering the entire window
< mst_> but somehow only the stuff that lands in the first of the 4 clipping rects actually shows up
< mst_> so i have a gradient along the top of the window, but other 3 borders are un-painted (very ugly)
< mst_> as i already mentioned earlier today just removing the clipping lets whole window be painted
< mst_> actually it is broken in LO 3.4, master, AOOo 3.4, havent tried anything older
< mst_> could it be it's an X problem?
< mst_> am running on F16 which is probably some bleeding edge stuff
< mst_> if i start it in Xephyr i get all gradients
