So 2.3 IS ABSOLUTELY FABULOUS - I've got much greater performance and far less bugs than 2.1 or 2.0 and I'm really digging some of the new options.
Okay so some people (me included) found the bug with the incoming call screen being off-center, clipped in the middle, or scrunched up over the side.
This obviously isn't a perfect fix but I installed the RedmanX Urban theme and it's seemed to have cleaned this up.
I have previously not installed the Urban themes but after trying this I really am finding it kinda nice. It's got a huge array of colors in the icons and I'm normally looking for a sleeker, minimalist (and dark) look - I was using Red Glass for 2.1 prior to 2.3. Pro's: Animations awesome, fixed call screen bug, nice emoticons/icons. Cons: Crazy colors that don't really follow a particular theme.
I'll check out RedmanX's other themes, hope they have the skippy as others.
Anyway, Yeah. Download a theme. Fixes the issue.
