Is the checkerboard regular or does it have 'smudges'? (hard to tell from the video)
Of course WinUAE won't emulate this (zeroing all memory) because bit stripe patterns are random.

However my are only guesses, I haven't looked at the demo code

A new test on Hard should be done this weekend (maybe) to answer your question. I read your explanation carefully.
You say that WinUae does not emulate this " effect ". Is it because it's impossible to do it ?

Thank you also for your Fix of the Turnips demo. I made a big mistake (for the report in the Beta post) by not taking more time to check ( and not to commit this unfortunate mistake ).
