screen problem - text is flickering
I have a problem with my gtab. the screen is kind of flockering. Not the problem with the screen flicker when the tab is low on ram, which was solved with the latest kernel. It is some kind of ... grainy effect. I notized first when I read a Pdf file where the background was black and the letters white. The letters were a little bit moving, as if the pixel were not constant. then I notized it is the same in the taskbar when on landscape, but not on portrait. the numbers of the time were grainy. furthermore the letters of the Apps in the Appdrawer, grainy but only in landscape, not portrait.
How can I solve this problem?
