I can confirm this regression. The lower of the bumbmapped balls has
some bitmap over it which flickers.
This is what the demo docs say of this screen:
1. Double Hires-Bumpmapper
This effect is based on hardware scrolling and screen
splitting. Two individial bump-mappers are rendered and
brought on screen to the correct position using the hard-
ware-scrolling, and in the middle of the screen, the
second bump-mapper's screen is shuffled in.
No chance to do it this quickly with a 320 x 200 bumpmap
on the ST in this resolution.
The problem is there also with Hatari version from 12th of this month,
so it's not completely recent.
