Unfortunately, that report has been diluted by a bunch of Cairo problem reports that I believe have nothing to do with the underlying problem. Pay attention to comments up to #5, then read the rest realizing they may be about a different bug.
If I were an X programmer, I'd attempt to write a small test program to duplicate the problem.
I don't think that the bug is related to Flash: I get it without having Flash on my system. I do think that Flash makes everything worse :-)
Again, I point to this bug report: http:// bugs.freedeskto p.org/show_ bug.cgi? id=21583
