Description Jamey Sharp 2006-03-05 05:45:47 UTC 
Xvfb from the Debian-packaged version of X.org 6.9 (6.9.0.dfsg.1-4) consistently
receives a SIGSEGV when running any of x11perf's -aa4trap tests. The -aa1trap
tests are fine. This bug happens at 8-bit, 16-bit, and 24-bit color depths, and
seems to be screen-size independent. X.org 6.8.2 didn't have this problem, at
least in the Debian packages.

The sane-looking part of the backtrace follows. Unfortunately I don't have a
copy with debugging symbols handy.

#1  0x080af8bb in fbRestoreAreas ()
#2  0x080b4184 in fbRestoreAreas ()
#3  0x080a0769 in fbComposite ()
#4  0x080f51c1 in miWideDash ()
#5  0x0816487d in miCompositeRects ()

I don't care much about this bug since I'm only trying to test Xlib performance
and I'll just skip those tests, but I wanted to make sure to get a bug report filed.

Sorry about the phenomenal bug spam, guys.  Adding xorg-team@ to the QA contact so bugs don't get lost in future.

    Add support for x4a4 format (depth 4 at 8bpp). Bug #6325.
