The issue persists, if the user navigates to a second website the page loads under the current viewport leaving the content displayed. But now the viewport is not fixed, you can scroll the page up/down. Also is not reproducible if the page is reloaded.

Can we reproduce this using landscape, but no hardware keyboard? Also, can you retest this with a new nightly? (we landed a patch to fix "handheldfriendly" conflicts)

I can reproduce this using latest Nightly Fennec/15.0a1 (2012-05-06) on HTC Desire Z(2.3.3.) whit the initial STR, although the behavior is a little bit different. The second page is not loaded at all only a blank page is displayed, if the device is rotated from landscape to portrait only the view-port is updated leaving the rest of the page blank. After reloading the page a blank page appears. Please see the log file.

The issue is not reproducible when using landscape mode without opening the hardware keyboard.

I was able to intermittently reproduce this bug on Droid 2. Sometimes the page will reload and scroll, but will not paint the page as you scroll down. Sometimes the page will repeat parts of the page.

This seems like a graphics invalidation problem where the browser has some old state from portrait mode that did not get updated when the HKB caused the AwesomeScreen to rotate. Rotating the device without opening the HKB does not seem to cause the problem.
