Public bug reported:
I've experienced some times now that when I load big images in Firefox,
the X server hangs. This occurs with a default Firefox profile, and for
example reproducible on http://sortvis.org/algorithms/bubblesort.html
(needs JavaScript). In this case, Xorg goes up to 100% CPU, and I does
not react to key presses (except when using the SysRq shortcuts to kill
it). I have a backtrace (see gdb-Xorg-direct.txt), with Xorg started
from gdb as root, and then browsing Firefox to the mentioned URL. From
the backtrace, it seems to be related with libpixman; however, when I
install libpixman-1-0-dbg to get a reasonable backtrace, the X hangs do
not occur anymore...
I am currently using Ubuntu Lucid LTS, with Firefox 3.6.18+build2
+nobinonly-0ubuntu0.10.04.2 from lucid-updates.
