Issue

After upgrading from Windows XP to Windows 7, running Matlab on a remote Linux computing server may run slowly when using X-Win32.

Solution

Disable offscreen pixmap support in Matlab.

How To

In your unix home directory, there should be a file called 'java.opts'. If it does not exist, create it.

Add the following line:

-Dsun.java2d.pmoffscreen=false

Then re-start the X-Win session.
