Screenshot showing garbage area after scrolling to the right.

Example application for testing: TV Browser (see screenshot)

When scrolling to the right, the contents of the scrolled area become garbled.
Moving the mouse pointer over elements in the garbled area apparently causes a
redraw of that element, fixing the issue, but the other elements are not
redrawn.

This does not occur when scrolling to the left. If the area is garbled and one
scrolls to the left, everything is redrawn and appears correctly again.

This may be confined to java applications, and I only noticed this in tvbrowser
(http://tvbrowser.org). Unfortunately I don't have any other java applications
available to test.


Reproducible on the following hardware:
ATI Technologies Inc Mobility Radeon HD 3400 Series
ATI Technologies Inc Device 6719 (HD 6950 Cayman)
