How can I solve this? I don't want to use another custom ROM.
You can try to disable screen dimming as this seems to be problem on
some custom ROMs. Of course, it is not a perm. solution, but could
help temporarily. We'll be looking on some solution for those roms.

Thanks for the answer!
Dimming the screen works. But I have a bad feeling about a screen that
is turned on whole night.
