Display issues when on CM related roms

view story

http://forum.xda-developers.com – Hello everyone I have a problem that I couldn't find answers.When my p7310 is on CM9,CM10 or other cm related roms,the start animation keeps flashing(just like the display issue for the cmw recovery,if some of you know that).Just lock and unlock the screen it will get back to normal,but it's still kinda annoying.Plus when I turn off the tab it will automatically turn on.No this kind of issues when on stock roms. If someone can help me,I do appreciate it.I have searched the forum but I didn't get the solutions. Thank you. (HowTos)
