EXA is better if you are using a compositing manager. However, I 
recently discovered an incompatibility between core EXA memory 
management and the openChrome driver. You might view it as an openChrome 
bug or a core EXA deficiency, but it would take a huge effort to fix up 
the openChrome driver.

You need to patch the X server to use EXA. See the wiki EXA page for 
details. I'm making a separate announcement on this. The patch should 
hopefully fix the cursor  glitches.
