"Flashing Rectangles" on screen??

[wlrottge]

I just got my XV-6900 last night as a replacement for my dead i-760. (fyi, i was told that they're being recalled).

I installed the usual slate of apps that I like (opera mini, skyfire, sktools and live search). I'm running the "stock" ROM b/c I want to play with it before I decide to start REALLY screwing with it.

I did some performance tweeks based on this thread:

I only performed items 4-8 since I don't have a key for SKTools yet.

Now when I start the phone, bring up the cube or close/open some apps I get a couple of flashing rectangles in the middle of the screen.

I've gone back and restored the defaults and done a soft reset but I still get the flashing rectangles.

Thoughts/suggestions??

TIA
