It seems that the problems related to the graphics subsystem occur often on
laptops.

We have already had reports of weird problems occuring on GeForce2-based
cards. Sometimes upgrading the drivers makes them vanish.

Maybe related to the new graphics mode fetching code, although I do think it
is correct.

Try the following test: in src/win/wddfull.c, replace every reference to
'gfx_directx_fetch_mode_list' (lines 56, 94 and 127) by 'NULL'. Does the
problem then vanish ?
