stock 4.4.2 bloat causing UI to lag in LinkBubble, touch-typing; until 'clear RAM' topic
To be precise, this isn't an issue of not having enough RAM (500MB free pre-clear), this is an issue of "some LG apps" causing touch-input-handling to 'slow down'.

since making this post, I found myself disabling and uninstalling many stock LG apps (Weather, Unified EULA, Slide Aside, Smart Screen, License Provider, LG Backup, Dual Window, LG System Server, LGATCMD Service) all the way until I got to com.lge.provider.systemui, at which point the notification bar stopped working (lol).
The REASON I did this was because each time I found the lag, I also found the corresponding app/service using about 10% CPU when watching it in OS Monitor, and kill/resetting it in OS Monitor would solve the issue.
You can replicate this most easily by installing LinkBubble and when the UI seems to be going a bit slow, opening it up-- and then drag the bubble around. You should see it tracking behind your finger, but if you follow it with your eyes, you won't see it tracking SMOOTHLY. Then, clear RAM/recent tasks, and try again: now it tracks smoothly.
The reason this is a big deal: the thing that causes LinkBubble to hitch along as it's being dragged, ALSO interferes with tap-typing on the keyboard, causing keys to be misread or, in the case of a swipe-style keyboard like Swype or Google Keyboard, to interpret fast typing as swipes for a word.
Has anyone else experienced this?
This happens on a completely stock ROM install.
