Xorg is crashing immediately when opening these two images in Firefox: http://upload.wikimedia.org/wikipedia/commons/9/9f/Systemesolaire2.jpg http://photojournal.jpl.nasa.gov/jpeg/PIA16700.jpg In journalctl I see this error: Dec 30 16:31:56 udderly gdm-Xorg-:0[1093]: Xorg.bin: glamor_largepixmap.c:787: glamor_merge_clipped_regions: Assertion `temp_priv->type != GLAMOR_TEXTURE_LARGE' failed. Here's a relevant thread: https://bbs.archlinux.org/viewtopic.php?pid=1473196 Linux 3.18.1 xorg-server 1.16.3 xf86-video-ati 1:7.5.0 HD 7950
Okay, I commented out this assertion: http://cgit.freedesktop.org/xorg/xserver/tree/glamor/glamor_largepixmap.c?h=server-1.16-branch#n787 Not crashing anymore and the images seem to be displayed correctly! Is it a good idea to leave so many assertions in a production code? :/

Created attachment 111526 [details] Loaded picture properly displayed
I found a way to crash Xorg when the assertion is disabled: - open one of the two images - force reloading with Ctrl + F5 - while it's reloading resize the browser window to force redrawing.

Also crashes X with glamor+modeset on intel.
Comment #2 (1st attachment) is definitely a glitch, picture is displaying fine with SNA.
It seems like you're not testing with the master version of the X server code? We fixed a bug like this back in August, but that fix is only on master.

Can't confim if it's fixed.
I can't reproduce the crash with xserver Git master. Reopen if you can.
