Attachment: Visual artifacts as shown in about:support

After a long running session I begin to get fairly severe visual artifacts in my browser. It's possible this is due to OOM, given the long running session. Though given my lack of familiarity with this area, that may be a red herring.

Running into this about once a week. Latest incident happened after current browser session was running for about ~6 hours. Memory report from this incident to be attached. About:support contains more of the same, notably stuff like this:

Looks like this is a possible dupe, or at least related to Bug 1163440.
