OS Monitor causes whole system stuttering on Xperia Z3 #84
Description
Yes, I know it sounds weird.
I had a problem with my Z3 (stock Marshmallow) where it would freeze up for a fraction of a second every few seconds. I've tracked it down to OS Monitor: those stutters seem to happen only when it's polling the system. There's a bunch of lines like this printed to logcat when that happens, perhaps it's related:
