Huge thanks to the one who can help me solve this issue! (Home button delay)

[vPro97]

An explanation of the issue:
When I press the home button, the home button lights up, but there's a lag between the phone registering my touch and actually going "home". This video sums it up nicely: https://www.youtube.com/watch?v=45J4dbN0mXI
Occurs almost every time, it's more prominent with 3rd party apps but there's even a delay when going home from "settings".

What I am running
Currently on OptimusG3 1.4 with Dorimanx 8.5.2.

What I've tried
Changing ROMS. The only ROMs where this issue doesn't appear are on AOSP roms.
Disabling G3TweaksBox and Xposed in general
Tried Nova Launcher (which I now use as my primary ROM)
Freezing the Default LG launcher
Uninstalling the default LG launcher
Speeding up animations.

Any help would be greatly appreciated!

UPDATE!
The issue seems to be apparent on Nexus 4 too, found this thread: http://forum.xda-developers.com/nexus-4/general/home-button-lag-android-4-4-kitkat-t2527703/page17

Switched to ART And now it's smooth but now I don't have xposed. Damn.

Still searching for a fix that doesn't include switching to ART

UPDATE:
I flashed the nexus 4 qualcomm dalvik libraries and I'm seeing a massive improvement. It's not entirely fixed, however. I still notice the animation stuttering, but overall it's much more fluid. If anybody knows how to eliminate this issue completely, let me know.
