Black screen after boot in android 11.05 LEB build

Hi,

I just tried android-leb from 11.05 release on panda board. I have a philips HDMI tv connected to the board.

I see the following things during the boot(in the same order):

1. Top row of the HDMI is filled with blurred images of green coloured android logos. -> Unclean.

2. I get nice boot animation screen.

3. Black screen appears, with a icon named "All" on the very right bottom of the screen. On clicking this icon I see various pre-build apps. I can start the apps, hardware acceleration is too cool but what is this black screen issue?

Any pointers on what could be wrong?
