Oh wow.....I have been searching everywhere for this. I have the EXACT same problem in Fedora 10. I tried setting the display to monochrome, but this did not help. Can anyone please help with this issue?!?! It only happens to me when viewing a large file (>2000 lines) in the matlab editor (i.e. the same file scrolls fine when viewed in gedit). PLEASE HELP!!

Hi Seth, Dene,

Please try the following and let me know if it solves the problem: create a java.opts file in the directory from which you start MATLAB containing the following line:

-Dsun.java2d.pmoffscreen=false

Let me know if this solves it. Thanks,
Jared
