Can you explain in detail what exactly the change in behavior for =
FULLSCREEN_WINDOW will be, for someone not looking at the patches?

I'd like to propose changing ALLEGRO_FULLSCREEN_WINDOW so that it =

here and there but not as bad as making ALLEGRO_FULLSCREEN separate from =
ALLEGRO_FULLSCREEN_WINDOW and ALLEGRO_FULLSCREEN_VIRTUAL. IMO it should =
have been that way from the start, as a modifier.
I still didn't figure out why alt-tab doesn't work but this is by =
far better than ALLEGRO_FULLSCREEN or ALLEGRO_FULLSCREEN_WINDOW where it =
doesn't work either. Will try and figure it out eventually.
Attached the patch, if there are no legitimate objections I'll apply =
it soon. I'll add documentation as well.

Virtual fullscreen is supposed to create the display using the =
window=20
manager to create a fullscreen window in a different way than =
"fullscreen=20
window". If we could figure out why KDE shifts the window up =
and XFCE the=20
window doesn't cover the panel, then it would be the best =
option (of=20
course=20
we'd then have to add a properly scaled buffer as you said.)=20

Apologies if this is obvious from the patch (I still only =
glanced at=20
it), but I was under the impression that 'virtual =
fullscreen' was merely=20
'fullscreen window' with some letter-boxing transformations? =
If so, why=20
is there a difference between the two?=20
If there is a difference, does the 'virtual fullscreen' work =
all the=20
time without compositing too?=20

Ok. I've already decided yesterday I'll probably abandon =
this patch=20
anyway,=20
but if it's possible and worthwhile to fix who knows.=20
The problem is with all three fullscreen types there are =
problems on=20
Linux.=20
1) Real fullscreen=20
KDE: shifted to top left corner=20
Unity: Needs CCSM installed and switch toggled=20
XFCE: works=20
2) Fullscreen window=20
KDE: Hangs the entire system=20
Unity: Can't alt-tab out=20
XFCE: works=20
3) Virtual fullscreen=20
KDE: shifted up about 20 pixels=20
Unity: works=20
XFCE: works sometimes depending on panel positions=20
It's freaking disgusting. The only thing that actually =
works is if you=20
disable compositing, then fullscreen window basically =
works.=20

Primitives and transforms have always been different =
for me. Paul,=20
what's the reason behind this? For example scaling =
everything up=20
still=20
results in crisp lines etc?=20
Of course it does, primitives are drawn using polygons =
and they are=20
going to use screen pixels (i.e. the actual =
resolution). It's=20
impossible=20
to emulate a scaled mode setting with transformations =
with respect to=20
how the primitives are drawn.=20
That's why you always use an intermediate bitmap that =
you then scale=20
up=20
if you want large pixels with your primitives. If you =
really want a=20
virtual mode in Allegro, that is the method you need =
to use.=20
-SL=20
I should note that this is not unique to primitives, =
since bitmaps are=20
drawn using polygons as well. E.g. drawing a bitmap at =
fractional=20
coordinates will look different on a virtual fullscreen =
and a real=20
mode.=20
This is even more easily seen with rotated bitmaps.=20
