             Bug #: 44014
           Summary: [RV350] Viewing some (latexbeamer generated) PDFs in
                    Okular in Presentation Mode causes massive, persistent
                    screen corruption
    Classification: Unclassified
           Product: xorg
           Version: unspecified
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: major
          Priority: medium
         Component: Driver/Radeon
        AssignedTo: xorg-driver-ati at lists.x.org
        ReportedBy: mrsteven at gmx.de
         QAContact: xorg-team at lists.x.org


When I view some PDFs that were generated with latexbeamer in KDE's Okular, the
screen gets corrupted. The corruption is not visible during the presentation
itself, but after the presentation the title bars are garbled and some fonts
are corrupted. I'll add a screenshot demonstrating the problem. This happens
with KWin (no matter if compositing is enabled or not) as well as with fluxbox.

One PDF that reproduces the problem reliably for me can be found here:
www.cirmmt.mcgill.ca/activities/workshops/training/latex/details/pdf-slides

I think it is a problem with the kernel module, because in some cases the
screen is still corrupt (but to a smaller degree) after I restarted the X
server.

Both kernel and X log show nothing indicating the problem.

Here's a list of the relevant packages installed on my system:
 $ emerge -pv xorg-server xf86-video-ati gentoo-sources mesa okular poppler

These are the packages that would be merged, in order:

I had this problem also with okular 4.4.5 and kernel 3.0.x (and as far as I
remember also at least 2.6.39.x).
