Steps to reproduce:

I pasted text in a textarea of an IMDb submission page with the middle mouse button.


Actual results:

There was an incorrect redraw below this textarea. Snapshot attached.


Expected results:

A redraw wasn't even needed AFAIK.
I could reproduce it two other times. The last one was not with a middle click, but when clicking on a form button.

When switching the desktop and coming back, the incorrect rendering is still present, but scrolling makes it disappear.

Editing text in StackExchange yields similar problems (always reproducible). I'm not sure whether this is related.
