Tested on nightly 2011-10-05 using Droid X, screen resolution 480×854. This is an intermittent checkerboarding display issue somewhat similar in appearance to Bug 681621, but this may not be related. (There is no faulty/erratic panning as in that bug, and the problem disappears when panned.) Similar, though, was that this also took a while to locate a reproducible case, I've noticed this sporadically when zooming and occasionally when panning left/right on other sites since at least 8.0a or so. Steps: 1. Switch to portrait mode. 2. Go to http://qdb.us/307110 (note: language) The page displays correctly, as shown in Attachment 1 [details] [diff]. 3. Double-tap to zoom-to-fit. There is some page corruption shown in Attachment 2 [details] [diff]. 4. Long press the huthuthut... nonsense to select it. The page display is now significantly checkerboarded as shown in Attachment 3 [details] [diff].
I've lost wifi access, the attachments probably won't be here til later tonight.
I was able to reproduce the issue. Switching to new. Need to take a look at other bugs as followup.
Status: UNCONFIRMED → NEW
Ever confirmed: true
This bug occurs randomly when panning or zooming even when not selecting text- it may be because of bug 674405 causing that particular movement on step 4, but I don't think it is otherwise related (bug 674405 makes no mention of checkerboarding).
