             Bug #: 49165
           Summary: OpenOffice fails to display anything on screen when
                    using cairo 1.12 (1.10 works) and enabling hardware
                    acceleration in settings
    Classification: Unclassified
           Product: LibreOffice
           Version: LibO 3.5.3 RC2
          Platform: All
        OS/Version: Linux (All)
            Status: UNCONFIRMED
          Severity: major
          Priority: medium
         Component: Presentation
        AssignedTo: libreoffice-bugs at lists.freedesktop.org
        ReportedBy: eric.valette at free.fr


The bug has been initially filled to cairo 
<https://bugs.freedesktop.org/show_bug.cgi?id=49118>

But after careful analysis, it happens that libreoffice creates surface of 0x0
size which is forbidden in the specs (Xlib requires at least 1x1) and correct
the size before displaying it.

Unfortunately, a change in cairo to be complaint with the specs breaks
libreoffice slideshow. There are now a good dozen of bugs in debian and until
cairo 12.1 is available, it could be wyse to fix in in 3.5.3.

In the link above you have a full backtrace that exhibits the call path for the
0x0 size
