I just upgraded from vmd-1.9.2 to 1.9.3. Running on Ubuntus 16.04, AMD
64-bit.

  The new version seems to work (I havnen't put it through all of its
paces), but when I start up, I get a slew of error messages (except
pasted below).

The first error seems to be a shortcoming of NVIDIA GL libs; it may by
inocuous.
The second type of error (there are dozens of these, only the first two
shown) invoolve
the OptiXRenderer.

I'm not aware of any functional consequences of these errors. But one
doesn't like to be greeted by a bunch of error messages when starting a
program.

Can anyone explian/remedy whatever is going on here?
