Description Bryce Harrington 2011-12-08 17:35:51 UTC 
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

hi Bryce,

thanks for reporting the bug, but you could have just saved me a bit of pointless work by putting me on CC: on this, or even just forwarding me a mail...

thanks Chris for fixing it so quickly :)
Comment 8 Björn Michaelsen 2011-12-09 11:21:44 UTC 
@mst: Sorry, I should have pinged you about it, but it came up spontaneous on IRC yesterday at 2am local and I didnt bother. Bryce was really proactive on this one ;)
Comment 9 Bryce Harrington 2011-12-09 11:30:14 UTC 
Think this might be the first time I've seen someone complain when a bug got fixed *too* fast.  ;-)

That is strange. Is this bug really fixed ? I cannot find the commit in master and libreoffice-3-5 branches.
My bug report bug 44210 has been done *after* this one has been closed and on my own build LO 3.5.0 beta.
Please, could you provide the link to the commit?

Thank you very much.

Sorry I should have read more carefully the comment by Stephan Bergmann in bug 44210.
So it is a bug in X not in LibreOffice and resolution should have been NotOurBug.

No workaround possible in LO ?

Best regards. JBF

Jean-Baptiste Faure:

please note that this bugtracker is used not only for LibreOffice but also for X.org, and its drivers, where this bug has been fixed.

in Fedora 16 the driver is fixed now.

Oups, sorry. I did not see that a bug LibreOffice was marked as duplicate of a bug X.

Best regards. JBF
