Hi,
Thanks for the bug report.
It's entirely possible that this is caused by the TLS issues that Tor
pointed out. If so, they may be fixed in the tls-fixes branch of this
repository:
git://anongit.freedesktop.org/~sandmann/pixman
There is a tarball with the fixes applied here:
http://www.daimi.au.dk/~sandmann/pixman-0.19.1.tar.gz
If that doesn't fix the problem, here are some questions:
- When the bug happens, what does this:
print mask_image->common.component_alpha
say in the debugger?
- Does the problem happen with 0.16.x releases?
- Does the problem happen when pixman is compiled with --disable-sse2?
Thanks,
Soren
