    Yes, I had found similar posts with a similar problem during my attempts to fix this issue and this was one of the first thing I tried in addition to maxing out the memory available for rendering.

      The memory is one thing. Did you ensure that the GPU is activated for your virtual machine ?

                  Hi, if you tested a vanilla Ubuntu 16.04.1, perhaps it needs an update to be able to display graphics properly:

                  sudo apt install libglu1-mesa-dev

                  (If that's not done, I cannot compile Qt programs. Perhaps that update helps displaying them as well.)

                    @hskoglund I updated libglu1, still no change. But thank you :-)

                      Hmmm, you could try installing Qt/Qt Creator in that Ubuntu VM, see if you can build and run any of Qt's OpenGL examples, for example Shader Effects (works ok on my Ubuntu VM).

                        Installed Qt on the deployment test system and it appears to be be able to run examples. However, the software I am deploying still does not function appropriately and I get the same error message when I enter that portion of the program.

                          What exact OS are you running ? What graphic card is the machine using ?

                                Hi just a wild guess but have you tried increasing the amount of RAM available on your troublesome VM, from 975.0 MB to say 2 GB?

                                    Are there any differences between the two machines ?

                                      Good news everyone! I figured it out. I needed to bring over the folder "xcbglintegrations" from the development plugins folder in Qt on the dev machine into the folder colocated the deployed program. Thank you again for all your help!

                                        Add
                                        export QT_QPA_PLATFORM_PLUGIN_PATH=/pathtoQT/5.x.0/gcc_64/plugins
                                        to ~/.bashrc

                                        source ~/.bashrc

                                        This works for me.
