Binary package hint: xserver-xorg-video-intel
Problem:
If I disable font antialiasing and attempt to access
http://launchpadlibrarian.net/29956668/crash.html in firefox my xserver aborts. This should not happen. The webpage should simply display the words "GOODBYE WORLD!" in very large text.
Note: text does not need to be very large. For example http://joe-editor.sourceforge.net/ also triggers the bug.

[Impact]
On certain affected hardware, results in X server crash when looking at certain kinds of large images.
[Development Solution]
Upstream fixed this bug in the 2.13.x version of -intel that we are shipping in natty.
[Stable Solution]
The attached patch is a cherrypick from the upstream tree that applies to the 2.12.x version of -intel in maverick. This patch is also the listed solution on the upstream bug report.
[Test Case]
On affected hardware, disable font antialiasing and load http://launchpadlibrarian.net/29956668/crash.html in firefox.
This will cause a segfault of the X server.
The fix will prevent this segfault from occuring, and instead firefox will display the words "GOODBYE WORLD!"
[Regression Potential]
Essentially none. This changes what happens when the uxa_pixmap_is_offscreen() call returns False. Before, it would fail the assertion test and terminate the X server. Pretty much any other behavior besides that is going to be an improvement!
That said, there are two subsequent commits on top of this one (which is why the patch in the description of this bug is different than that proposed). Near as I can tell these address other unrelated issues and so I'm omitting them for now. It is conceivable though that this patch provides an incomplete solution and those other patches should be backported too. But one step at a time; if this patch alone is sufficient to solve the issue it is the least risk way to go.
[Original Report]
Problem:
If I disable font antialiasing and attempt to access
http://launchpadlibrarian.net/29956668/crash.html in firefox my xserver aborts. This should not happen. The webpage should simply display the words "GOODBYE WORLD!" in very large text.
Note: text does not need to be very large. For example http://joe-editor.sourceforge.net/ also triggers the bug.

[Impact]
On certain affected hardware, results in X server crash when looking at certain kinds of large images.
[Development Solution]
Upstream fixed this bug in the 2.13.x version of -intel that we are shipping in natty.
[Stable Solution]
The attached patch is a cherrypick from the upstream tree that applies to the 2.12.x version of -intel in maverick. This patch is also the listed solution on the upstream bug report.
[Test Case]
On affected hardware, disable font antialiasing and load http://launchpadlibrarian.net/29956668/crash.html in firefox.
This will cause a segfault of the X server.
The fix will prevent this segfault from occuring, and instead firefox will display the words "GOODBYE WORLD!"
[Regression Potential]
Essentially none. This changes what happens when the uxa_pixmap_is_offscreen() call returns False. Before, it would fail the assertion test and terminate the X server. Pretty much any other behavior besides that is going to be an improvement!
That said, there are two subsequent commits on top of this one (which is why the patch in the description of this bug is different than that proposed). Near as I can tell these address other unrelated issues and so I'm omitting them for now. It is conceivable though that this patch provides an incomplete solution and those other patches should be backported too. But one step at a time; if this patch alone is sufficient to solve the issue it is the least risk way to go.
[Original Report]
Problem:
If I disable font antialiasing and attempt to access
http://launchpadlibrarian.net/29956668/crash.html in firefox my xserver aborts. This should not happen. The webpage should simply display the words "GOODBYE WORLD!" in very large text.
Note: text does not need to be very large. For example http://joe-editor.sourceforge.net/ also triggers the bug.
