OK Harry, I really appreciate your efforts to identify the cause of these problems. I'm sure it is something I forgot to adjust when I recently changed the way pvQt fits the texture image to the source image, but I can't see it -- and 0.5.72 runs fine here on 3 machines under Windows and under ubuntu Linux on one of them -- so I have nothing "debuggable" to work with.
These kinds of symptoms indicate that I am passing impossible requests to OpenGL, only when loading cube face textures or trying to display them; and that the degree of impossibility changes with the internal state of the video system. Memory allocation problems are the most likely direct cause, but there could be others. They aren't related to power of 2 textures or other early version limitatitons, because most people who report them have OpenGL 2+ systems. The code that handles the cubic projection is largely separate from that for 2D textures, which covers all the other projections, because the cube texture mapping is built into OpenGL whereas I use my own texture maps for the rest.
