Ugly Call Screen Help

I am on Sultanxda's CM13 rom + kernel and am having a great experience performance and battery wise, but this is something strange, the caller screen that comes when you call somebody or receive a call . Its ugly and its green. I tried installing google dialer from playstore but still no effect. Refer screenshot.:crying::crying:
