Damn, I actually loved CyanoGen but reflashed to the TeamChicken mod or whatever because of the screen issue.. It was driving me nuts. Is there any way to change that if I go back to Cyano? Also I don't know about other peoples phones but my phone was kinda laggyKept taking like 2-3 seconds to respond to some things.. I don't know why.
Ya just reflash it like any ROM and just tap the phone when its asleep xD . Put on SD card > NAND Backup (VERY Important) > Wipe Flash > Enjoy

And as for the lag idk, my phone actually got much faster with Cyano, I couldn't even software decode any videos on stock because of all the bloat running. After overclocking to 787 it got WAY faster than normal.
