o dear. this is using an old intel chipset graphics hardware.
and you probably installed the worst possible driver.

there is not much hope. outside of supporting compositing,
the developers for the intel chipset graphics OpenGL support
don't seem to cae about it much. i've been using laptops with
intel chipset graphics for many, many years now and the
situation going back and forth between almost acceptable
and absolutely horrible. if you want to keep doing serious
VMD work on a laptop, get a different one. even if the driver
will become better, its performance will still be lacking.
