408587 - page hangs X server for ~15 seconds

Status: RESOLVED DUPLICATE of bug 371867

(Core :: Graphics, defect, P2)

Description

[David Baron :dbaron: (⌚️UTC-4, no longer working on Mozilla)]

Loading the page http://www.fly.faa.gov/flyfaa/usmap.jsp hangs my X server for 5-20 seconds at a time -- it seems like each repaint of the page causes the hang to repeat.

Steps to reproduce: load http://www.fly.faa.gov/flyfaa/usmap.jsp and scroll around

Actual results: X server hangs for a period of time -- to the point where Caps Lock doesn't work for 15 seconds, the multiload-applet-2 system monitors on my toolbar don't update, etc.  And then the system comes back (particularly if that window is no longer visible).

I'm running Fedora 7 with the fglrx X driver from Livna, but without the kernel module:
xorg-x11-server-Xorg-1.3.0.0-9.fc7
xorg-x11-drv-fglrx-8.42.3-6.lvn7

Regressed between 2006-04-06-04-trunk and 2006-04-07-04-trunk.

Bug 324967 seems most likely, unless that's when cairo was turned on for Linux nightlies (would that show up in the checkin list?).

For me, this regressed between 2006-10-25-08-trunk and 2006-10-26-09-trunk, which corresponded to enabling cairo (based on about:buildconfig)

...actually

Er, actually, those dates are when cairo was enabled for Firefox nightlies (per about:buildconfig although nothing I could find in CVS).
