Tried it, and using the options (XaaNoOffscreenPixmaps from
/usr/local/mozilla-firefox/README.OpenBSD)
Driver "intel"
Option "AccelMethod" "EXA"
Option "XaaNoOffscreenPixmaps"
the images in firefox3 are ok.
*However*, in contrast to i810, the driver can't be persuaded to use
1600x1200 by default, not even by using
Virtual 1600 1200
Modes "1600x1200" "1280x1024" "1024x768" "800x600" "640x480"
in each Display subsection in the Screen section (definitely including
the subsection for depth 24, which is my DefaultDepth and the depth
actually used, according to xdpyinfo).
Instead, 1280x1024 is used, even though xrandr *does* report 1600x1200
as available. It's not even 1600x1200 as *virtual* size, despite my
configuration ("Virtual 1600 1200").
Switching to 1600x1200 with xrandr *does* work, and that's my
workaround: doing that in my .xsession/.xinitrc early, followed by a
sleep 1. But it's not really nice. Why does 1600x1200 not work without
that workaround with intel(4), but with i810(4)?
(And why does X -configure select i810 over intel as driver, anyway, if
intel seems to be better?)
Kind regards,
Hannah.
