The flashing I am talking about is NOT a problem when we load textures. It
is a problem when looking at certain things that are
already loaded, i.e. a multigen model.
We could be looking at a model of a truck on the ground. The truck would be
rendered in greyscale. By looking at it at different angles, it can turn
blue, flash, and do all sorts of things.
This problem does not appear on onyx2's (running anything) or octanes
running 6.4. The software is different from onyx to octane, but the same for
an octane on 6.4 and on 6.5.x.
We notice that the app can hang when these problems appear.
We are using Vega 3.3 SP, along with performer. Has anyone encountered
problems with this and Octanes on 6.5.x?
