So first, the mandatory thanks for the rom, close to stock, no bloat, layers rules, love it, would marry it, blablabla.
After some playing around (had to make sure, it's not EX Kernel or F2FS), I can now report the following bug, which can be easily reproduced on other devices with this rom:
If you mirror the screen to a chromecast and turn your screen off, the Chromecast doesn't get into locked mode, instead, if you try to turn your screen on again, you just see your background picture appearing and disappearing in a loop. There is no other way from that point on, than to restart (restart menu still works) the (PureNexus) device.
I tested with a fresh install of the rom on a Nexus 5 and on a Nexus 7 2013 WiFi (flo), I also tested the latest Cyanogen Mod Nightly, with which this bug does not occur.
I tried to document the bug with "alogcat", the log is in the attachments, but I guess I ****ed it up, but hey, fingers crossed. :fingers-crossed:
