Thanks @SourceTrigger. I'll try building this and running it on OSX, Windows, and Linux some time today, just to make sure no unexpected weirdness shows up. If all goes well, this'll be merged after that. 😄 |

Excellent. Builds and works ok here on Win 7, Linux (Fedora 25 x64), and OSX 10.11.6 (non 4k/5k resolution though). Thanks for reporting this and getting it fixed. We wouldn't have even known about it otherwise. 😄 |

On macOS in 4k and 5k resolutions the program runs very slowly. For Qt to render via OpenGL, a QOpenGLWidget must be added.
