There were a lot of questions raised in the original report back in
January.  Here are updates....

I have been following the progress of another bug (288650) and noticed
that running the Java VM with a suggested option as a workaround:

java -Dsun.java2d.pmoffscreen=false YourProgramGoesHere

dramatically reduces the realtime graphics interactivity lag in my Java
Applications.  I will test this again when the Jaunty RC comes out in a
few days to see if I still need this switch.

As far as Audio problems that may or may not have been related
(apparently not).  The sound cleared up after I went against the
recommendations and switched audio from ALSA to Pulse in AVIDeMux.  Now,
the audio drops out every second for a moment in playback, but that has
no effect of the production results and affects no other applications.
Recommending that fix for bug (321028) seems to have completely solved
the problems for others, so I'll just test again on Jaunty.

The snowing effect remains; however.  I will see if I can capture it if
it still exists in Jaunty.  It looks just like an image file displayed
with the wrong rendering format or the wrong video configuration for a
moment when an application first starts - but then clears up quickly.
