Bug Description
[Impact]
Minor but noticeable cosmetic issue in the welcome screen for libreoffice. Caused by a regression in UXA compositing. 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.
[Development Fix]
Fixed upstream and in precise with patch 103_fix_
[Stable Fix]
The same patch applies without change to oneiric, and is being proposed here.
[Text Case]
1. Open LibreOffice (any component).
Broken Behavior: Welcome screen looks clipped with some portions unpainted
Fixed Behavior: Normal welcome screen displayed
[Regression Potential]
We've been carrying this patch without issue for several months now. The fix was also pretty straightforward. I'd say even though this is a cosmetic issue, the fix has proven to be quite safe. We've had a number of reports against oneiric about this so it seems to be sufficiently annoying that it's going to be worth getting fixed.
[Original Report]
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.
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

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.

< 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
