nexus 6, android 5.1 - bug with call app

[AC Question]

Just installed android 5.1 on my nexus 6, everything works fine, just one problem: when i dial a number the panel turns black, i cannot see the call app, the contacted person and cannot control neither stop the call nor turn up or down the volume.

A bug on the very phone the ROM was designed for? Shame on Google. Try using a different dialer app until they fix it. Maybe 5.1.1 is the magic number. (And maybe pigs really can fly.)

My Rooted Nexus 6 facing the call app problem, this won't happen when you put on the bluetooth headset. I use Nexus Root Toolkits to flash stock android 5.1.0 (LMY47D) rom without wipe out data/caches. Master reset will help? any idea?
