Only things I've noticed were:
-FC when you select a color in any of the "Rom Control" options, not sure if anywhere else
-Also FC when you select a picture for the lock screen
-Odd rotation issue on the homescreen when the keyboard is out. Push keyboard back in, and it quick flops between landscape and portrait. Otherwise it stays portrait
-Doesn't seem like there's any difference between lockscreens, but that could just be me.
I wiped data+Cache+Dalvik+Battery before installing this rom. I was on CM9 with the latest modem. It says EL30 now, but I swear I was on...FB15?
Otherwise solid rom!
