My best recommendation would be to do a full wipe and fresh install. If clearing cache and dalvik did nothing and there is no theme there isn't much more you can get do. Wipe and reflash the rom, but when your phone boots let it sit for five or ten minutes to let everything stabilize
Edit: You will notice too you will get a lot of core process FC's after rebooting if you try to use the phone too quick. Even without a flash, you should always let your phone fully boot before unlocking/using it to let everything load.
