I had to revert a commit on the GPROJ Kernel to make it work correctly. Since Neightborhood Hacker's kernel is based on GPROJ, I bet the same commit needs to be reverted to make it work correctly. It has to do with the frame buffer driver, so it makes since why you would be seeing stuttering. When I'm available to make changes, like fix the two issues that have been identified, I will also look into compiling his kernel for this ROM.
I'm using it on my phone, but get some light stutters & screen tear while swiping in apps or in the launcher. really like the kernel tho :/ would also love to see an update for it. it's been long since it was updated.
