Random Dark Grey Screen on CM12.1

[Ragarianok]

Anyone else having this issue? There doesn't doesn't seem to be any method to the madness; it happens fairly randomly.

It's happened while:
-listening to music with stock CM12.1 music player
-using stock browser
-using Chrome browser
-watching video on YouTube app

It's almost as if the screen turns off, but it's still on. No status bar, no navigation keys. If it happens while listening to music or using YouTube, audio skips for a moment but keeps going.

This happens on the LG G-Pad 8.3, too (CM12/CM12.1 based and AOSP 5.1.1*)

haven't observed this on the Note 3 yet

Could be either a regression, issue originating in Android 5.1.1 (or 5.1) or something introduced by CM12* and backported to AOSP 5.1.1 ROMs

I suspect it's either related to Adreno drivers or Qualcomm stuff (G-Pad also has Adreno & Qualcomm parts according to http://www.gsmarena.com/motorola_moto_g_(2nd_gen)-6647.php )

since a CM11-based kernel runs fine, so it must be something in sauce (kernel sources)
