I just installed the latest version of openscad and started using it today
and I like it very much except for one thing.

I'm running it on an old MacBook Pro unibody running Ubuntu 14.04. This old
thing has two graphics processors. When I run openscad normally, on the slow
GPU it's fine, but when I try to run it on the high performance GPU (and it
is MUCH higher performance) using the optirun command it leaves most of it's
preview window alone (I can see other windows and my desktop through the
window, though I can't "touch" them) and it draws in a little 2 inch wide by
1 inch tall (estimated) area near the upper left hand corner of the preview
window. The image is not scaled to fit. I can see the x, y, z pointers so it
looks like the image is translated vertically so that the lower left corner
is within an inch or so of the upper left corner of the window as well as
being clipped at the top of the window and arbitrarily on the right.

I'm typing the "optirun openscad" command in a terminal window and there are
no messages of any sort appearing there after the command.

It does not depend on the file I am working on, it does it with a "new" file
also.

I have not seen any other application do this.

Any ideas what's going on or how to fix this?

I just learned that if I resize the application window until it is as small
as it will go, i.e. the preview window is reduced to that 2" x 1" that's
being drawn in, the content of that little patch is scaled continuously
during the process until finally the entire view seems to be contained in
that tiny window.

I don't know what's happening, but OpenSCAD does not take advantage of GPUs.
So just use the built-in one.
