Mouse tearing... or something? (mouse leaves marks across the screen)

[AlpineRaven]

I'm using Atkos 5i OSX.5.5 with ASUS P5GC-MX/1333 Logic Board with GMA950 video, no video card installed. 4 gb RAM.

 

 

See the picture above, It only happens with "heavy" applications like, imovie, iphoto, Microsoft word, Excel & Photoshop.. Its getting annoying, it only leaves 3 marks and will disappear when there is no "load".

 

How can i fix that?

 

If there is more questions that needs to be answered I'm happy to answer.

 

Thanks

AP

 

Oh never happened in OSX.4.11

Cheers
