Bug Description
I have the same problem as reported here:
https:/
When scrolling right in Java apps the screen becomes distorted. This does not happen when scrolling left.
See attached screenshot of TV-Browser where this happens normally.
After making the screenshot the distortion is away. Looks like the screen is redrwan after that.
Some more details:
In the above mentioned bug report the user has a AMD graphics card. I'm using the proprietary Nvidia driver, so I think it's not the graphics driver.
Since this only happens in java apps this must have something to do with openjdk.
This problem only exists with Unity (compiz) not with Unity 2D (metacity). So I think this is a problem with java graphics and compositing.

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)
