not sure that I'm sending this to the right mesa component: if not,
apologies and please redirect me

Starting with 10.6.0-rc1, mesa-10.6.x somehow breaks glamor (or it's
the other way around).

If I boot X11 with glamor enabled (`Option "AccelMethod" "glamor"' in
xorg.conf) and mesa-10.6.x, I get a black screen background (despite
"xsetroot -bg violet -fg white -mod 16 16" in my .xinitrc). Moreover,
xterms and in general all other windows have a black background; no
visible cursor in the xterms, but if I play with window exposure (by
lowering/raising them), I can see parts of them with the expected
appearance (eg xterm: white bg and violet fg).

If I run xrefresh, everything disappears into the black background;
then, if I focus the windows by moving the mouse upon them, the
decorations of the WM emerge (the windows' background remains black,

It seems to be only a matter of background/appearance, in general:
functionality of the different clients seems to be fine, as far as I
can say (eg the shells in the xterms do work fine etc).

Everything is restored to normality if I boot X11 with mesa-10.6.x and
glamor disabled in xorg.conf.

Also, absolutely no problem with glamor enabled and mesa-10.5.x

Here are my specs:

I have no idea which might be the problem.

I will be happy to provide any other information which might be
useful in this regard
