Hi,
I have noticed that when using GRUB_TERMINAL=gfxterm (that is, the
default option, which I think is gfxterm), full-screen flash
performance
is bad (on a 1440x900 screen it is barely ok, on a 1920x1200 screen
it's
terrible).
But if I put GRUB_TERMINAL=console, the performance drammatically
improves. I am seeing this on rawhide with a intel 4500MHD IGP (i915
driver).
I am unsure which is the best package to file the bug for: grub2 or
xorg-x11-drv-intel?
Confirmed with Thinkpad T500 and Intel 4500MHD, Fedora 17. If I hadn't seen this with
my own eyes, I wouldn't have believed this can be related. The bugzilla is here:
