Yes it does stutter as it appears but what I'm talking about is while its moving. I always get that issue right after upgrading to tango, and then I'm gonna be forced to hard reset because I don't like it stuttering, it makes WP look like its having a hard time rendering simple 3d graphics. Then after hard reset, capacitive buttons will not work, making me even more frustrated. So I'm back to 8107 with 2.5 bootloader since I don't really need tango, but what irritates me is that a simple update just messes it all up.
So anyway I can take a video of it for you guys just for a demonstration, I'll do it later when I get home and see what I'm talking about.
