Hi!
I was made aware of this by a FreeBSD user, but i suspect the
problem is not specific to FreeBSD hosts: If run on a 16 bit
display, qemu-system-sparc' video is messed up like shown here:

(pink, and uses only half of the window's width...) It looks okay
on 24 bit displays.
Thanx,
Juergen

I can confirm this happens under linux also. Never thought to try 24bit.

Looks you're telling QEMU that you've got a 16 bit buffer when it's really
a 32 bit buffer.
Perhaps we're mixing up bits-per-pixel with depth?

Perhaps this in tcx.c?
switch (ts->ds->depth) {
case 32:
f = tcx_draw_line32;
break;
case 24:
f = tcx_draw_line24;
break;
default:
case 8:
f = tcx_draw_line8;
break;
case 0:
return;
}
