Thanks, I had in fact found that reference and implemented it. Interesting thing is that if you read it carefully it is not a set of alternatives, having got the GPU in OpenGL mode you are still required to turn off GPU acceleration.
I also have an issue with AMD-GPU.. But here it's not a crash. It just simply refuses to use GPU, ever since 2015.10.1.
I tried the above for sh*ts and giggles, but it still won't allow me to enable GPU.
Here, it's Win10 AMD A8-3500M w/HD6620G integrated graphics.
I seem to recall that they had problems with AMD GPU acceleration when LR6/2015 came out, as well. I don't understand what it is about AMD, but this is getting tiresome.
