I had post at ubuntu forum and someone member suggested it as a bug.I am a newbie on ubuntu which I just installed it 2 weeks ago.
Everytime I play any movie files such as .avi , .mpeg it goes up to 100%.It play weel on .mp3 songs but when comes to video files it.
I had tested with all 3 player including Movie player but it still get 100% usage when visual effect is enable to normal.
It start to play and cpu usage jumps up to 100% , within a few second the surrounding getting grey out , very lag when opening any application even opening a text file.But the movie still playing and once I double click the player to maximize to full screen , it just stop there .The whole GUI movie picture stop with no sound at all.I had to press reset button on my pc to restart.Tried other player , Smplayer is even worst , I straight get black when goes full screen.

Went to youtube , playing any flash movie , still the same except
without gray out.But sometimes the whole flash video stop when full
screen.No choice , and I have to press again reset button on my pc to
restart ubuntu.

When I disable the visual effect to none , everything runs well , movie
, flash all runs below 50% cpu usage.

I really hope someone will help out to fix this bug.Thank you
