Home Screen redraw on 2.2

I've not seen this discussed in this forum yet.

I have been experiencing an issue that is starting to bug me. When coming out of an application using either the Home Key or Back Key, there is a significant delay in the screen redrawing. What I see is just the background and the row of phone, app and Web buttons. Feels like it gets worse over time. A power reboot seems to clear it for a while but comes back after a bit of use.

Anyone else noticing this?
