Cannot be reproduced on LibreOffice 3.4  340m1(Build:12). Thanks for the screenshots and description. I downloaded your test file and moved it around a little. There is no corruption at all. No objects become gray, discolored, or blank. Perhaps a patch has fixed it for my newer version of LO. Can anyone else confirm this? Thanks.

Tried 3.4, and now I am getting issues even with the splashscreen (see attachment). These seem missing redraws too.

Also tried downgrading the intel video drivers to the standard ones for my distro, no difference.

I wonder what is going on. Libreoffice (and openoffice - tested that too) appear to be fighting hard with my Xorg, and to forget redraws... but any other application is just happy on my system.

Puzzling.

[This is an automated message.]
This bug was filed before the changes to Bugzilla on 2011-10-16. Thus it
started right out as NEW without ever being explicitly confirmed. The bug is
changed to state NEEDINFO for this reason. To move this bug from NEEDINFO back
to NEW please check if the bug still persists with the 3.5.0 beta1 or beta2 prereleases.
Details on how to test the 3.5.0 beta1 can be found at:

Seems to be ok right now.

I believe it was not a bug on libreoffice, rather on the linux graphics stack.

Please mark as closed. I will open a new bug in case I run into new issues and I can distillate a test case.
