Description Clemens Eisserer 2011-10-31 05:49:24 UTC 
Running the SwingSet2 demo application, I can produce scrolling artifacts when viewing the "text" panel (can be choosen from the toolbar), by scrolling fast from top to bottom using my mouse' scrollwheel.

The problem does only show up when using UXA on my intel i945GM.

The curse of the fallback. Between Swine2D and WINE Looks like I have to accelerate stipples...
