Two things: it appears that Xorg isn't multi-threaded, and that there

Does the problem happen with Konqureror or iceweasel as well or only
Konqueror has almost identical symptoms, though slightly less severe.
Do you need the all-in-one-mega-app approach of iceape or
would Konq or iceweasel work for you?
I wish it were that easy to resolve. At this point it seems independent of the
graphics hardware but related to web browsing and images (and not plugins, java
various browser configuration settings. Nothing unusual appears in the system
logs or boot up messages. I will try a stripped down kernel and/or run a mirror
of the system on another motherboard to eliminate most hardware related issues.
My guess is that I will find the problem this way and it will not turn out to
be a user-space software issue.
If that doesn't isolate the problem, however, then I probably take a look at the
libraries. Except for debian-multimedia and custom kernels, all binaries pass a
debsums check against the latest debian archive. The following command lists the
libs that are common to both Iceape and Konqueror:
$ echo "`apt-cache depends iceape-browser|grep ' lib'`"+"`apt-cache depends
konqueror|grep ' lib'`"|sort|uniq -d
Of these, the ones that look like they could be related to browser images are
libjpeg62, libpng12-0, libxinerama1, libxrandr2 and libxrender1. None are
debian-multimedia replacements. There was a big library upgrade a couple days
ago but I've already overwritten my daily backup so I can't easily revert.
If and when I locate the problem I'll post the resolution here.
