From the peanut gallery:

I have a hard time swallowing the idea that there’s no way to determine whether accelerated graphics will work at runtime short of a seg fault.  Granted, 3rd-party bugs are always possible, but KiCAD should be able to check for libraries and features in order to successfully drop back to fallback graphics without seg faulting on anything but a truly broken system.  

All that to say it shouldn’t be necessary to default to fallback if we can do a better job at startup of determining whether accelerated graphics will work.

Then I remembered that I had had that problem in the past when I was trying out accelerated graphics.  But in the past, I was able to select fallback graphics from that initial dialog.
