Hi I installed Jaunty for my Mom the other day, everything went ok. Except if compiz is enabled (Which was by default) with a 45 minutes of usage it just it just starts to fail. Compiz starts to flicker and the effects are not so smooth some more, Until the point its freezes beyond any help. Its seems to run perfect with out compiz, though its very disappoint since in 6.06,8.04, and 8.10 (I am no under any proprietary drives nor I tweaked with the compiz settings)

Any Ideas?
