My Ndless 2.0 build doesn't work with Ndless 1.7.

What happens? Do you know which 2.0-specific feature you are using?

- reboots (rare)

I hope the shift of the screen will be fixed for the final release.
But I don't have any bug reports related to reboots, if you want me to investigate I would need more information.

The screen shift issue is actually caused by reads and writes from the screen i/o. A memcpy-ied screen buffer should be used for the reads. Could you check if there is anything like this in your code?

mViewer is using its own 16-bits screen buffer.

mViewer's viewer is using 2 buffers. The screen is refreshed by switching the buffers addresses.

But mViewer's browser is reading/writing directly on a single buffer...
And debug messages too...
