Yeah DivestOS ticks nearly all the boxes for me (eg call recording and custom gestures eg long press back to force close), however there were a few little niggles that custom ROMs have with other manufacturers - the camera is usually closed source so you can't quite get all out of it, and also I was having issues with pocket detection where a message or call would turn my screen on and then it would either answer in my pocket or mess with the audio player on the lock screen. Not had any of those issues so far with the Pixel.
However curved screens suck balls, and the cheap screen protector I got is already cracked lol.
Yeah others are saying it's to do with the keyboard, or rather that other keyboards seem to get around the bug. However it's only Jerboa that I have this issue with.
I'm using the standard Android Keyboard (AOSP), so it's not something you would expect to have errors. Don't really want to change as I'm used to it and have it set up for different nationalities (Greek for maths, couple other countries for their funky accented letters).
