When I drag and drop background into the scene it keeps loading and loading and nothing happens. In addiction, my defauld background is transparent and when I drag objects to my scene they are not showing. Few days before all was working correct. What happend? I downloaded new driver for my NVidia Geforce GTX 1050 day before my Dimension started working wrong. Could it cause the problem?
After installation the program told me that "Your system does not meet all of the minimum system requirements" but there was not any problems with using it.
Sorry for my english and thank you for your answers
Now I know what's going on!
When my laptop is on cable - dimension works correctly, when it's on battery - doesn't show background and models.
If you are on Mac OS especially there is a setting which will turn off your discrete GPU when you are not on powered cable to preserve batter. You'll find the option under the Energy Saver and can disable it to keep your graphics card enabled.
