I don't have the problem but it seems like a bug. HW may be slightly changed through the devices and the SW should deal with all the changes so it will be probably fixed in updates.
Finally, I made a new clear install with stable rom and the problem dissapeared! Then I returned back to my (favorite) developer and the problem returned back! So, I guess, that it has to do with the developer rom...
Make sure you go back to the dev ROM on your Pro, the stable isn't stable at all especially in concern with performance and heat. 5.7.27, a Pro only ROM, is the best so far.
