[hatari-devel] bad screen rendering with Falcon/TT + vdi ?

[Nicolas Pomarède <npomarede@xxxxxxxxxxxx>]

Hi

as reported here :
http://atari-forum.com/viewtopic.php?p=303493#p303489

Falcon with extended vdi resolution 1024x768 gives bad rendering.

I can see the same if I use 672x480 (instead of the default 640x400) : 
gfx are shifted on each line as if the correct number of bytes per line 
was not applied.

Same problem happens with TT mode and tos and extended vdi res of 672x480.

I'm not too familiar with VDI mode as I rarely used it, maybe I need 
some other config parameters ?

Note that only the Atari logo is distorted during boot. After that the 
GEM desktop appears and is correct, except only the top of the desktop 
is visible, the rest is just white.

The problem during boot might be because vdi is not used by tos this 
early in the  boot process ? After that memory test is correctly displayed.

Display is bad too under Hatari 1.9, but desktop was correct under 1.8 ; 
is this a regression ?
