I am running ubuntu 11.10 , GNOME Shell. After some amount of memory consumption, my Ubuntu starts displaying stripes all over my desktop and also in the native application windows like empathy, nautilus etc.
My system information is as follows,
Memory: 2.9 GB Processor: Intel Pentium Dual-core CPU E5200 @ 2.5 GHz Graphics: Intel® G33 x86/MMX/SSE2
Any help is appreciated.
