Since I rooted and installed TWRP and flashed the custom kernel that is required to continue using the stock ROM after installing TWRP, anytime I hold certain things (items on home screen in Nova), swipe up from the Navbar to bring up the ring, or tap the little gear in the sound popup (to show all the sound options instead of just ringer), my phone freezes completely for 2-4 seconds. It's especially bad with Swiftkey, which freezes after each button press. I don't actually use Swiftkey, I just wanted to see if it had changed since I last used it and it seems to have gotten worse. Holding or tapping anything in the AOSP and LG keyboards is fine, though. Bringing up recents by holding the home button works as usual without freezing.
Anyone know why this is happening or know of a fix?

EDIT: Only AOSP keyboard works, LG freezes after every press, just like Swiftkey.
EDIT: Discovered that disabling the "LG System Server 1.0" app was the issue.
