Default CM11 on GT-S6500D causes white screen on standby mode

All I know is that there is a white screen error in http://forum.xda-developers.com/show...575127&page=28 when the phone goes into standby. The only thing that fixes it is a restart. Unfortunately, I do not have a logcat...

After switching to the CM10.1 made by bleached, the error got fixed, and the camera is working too.
