When I put "Bitsy" to sleep and then wake it up the display driver does not reinitialize properly. Screen is all red, disproportional and chopy. Using 5.7" Sharp TFT 320x240, in portrait mode 16bpp color.

We've recently updated the display driver to better handle display rotation and other driver features in sleep mode. Can you tell us what build of CE you're using? (build #, size)

I am having a similar problem using a Hantronix display. When I wake up the Bitsy, the image gets a bit fuzzy and there are a few vertical lines of complete garbage. I should mention that I am rotating the display 270 degrees. I am not sure if that has any effect on the wake-up distortion, but I thought it may good to know. Here are the debug messages I get while booting:

Processor Initialization Table read.
Waiting for memory clocks to stabilize.
