Hi,

I'm not really familiar with VDI, but at 1st sight, I don't see how the 
interrupt changes in video.c could be related and create such bitmap 
shifting.

In fact, with falcon mode, tos 4.04 and 1 plane in VDI, I get only the gem 
menu line and the rest of the screen is a "grey" pattern, but sthg is 
definitly drawn on the screen.

Also, running under hatari 1.1.0

./hatari -s 4 --machine st --vdi-planes 4 --vdi-width 800 --vdi-height 600

gives the same results as now with devel version (yellow colors).

Same result under hatari 1.1.0 and devel :
./hatari -s 14 --machine falcon --tos ~/Emul/ST/steem/tos404.img --vdi-planes 1 --vdi-width 800 --vdi-height 600

(with some nasty illegal accesses in the console)

And same with vdi planes set to 4 : illegal accesses and eventually 2 bombs.

So, I'm afraid something is broken since at least version 1.1.0 :(
