I spent a little time playing with the 'black artifacts with bump mapping and GGX shader yesterday.

OK - have spent a little time looking at the code.

Having looked at the code it appears that the color space initialization for the texture is done in
function: paint_brush_update (particualy lines 239->261)
I have done a little further investigation.

Although I am sure the change will fix the crash. What I am unsure of (as I don't really know the code) is if calling the function txt_do_undo with text->undo_pos with a value of -1 is a code design feature of if it indicates something else is not right somewhere else.
Thanks for the changes/ However, the basic test scene is still crashing for me in Debug,

You probably know this already - but just in case - I tested it with the Principled shader and the same problem occurs with multiscatter GGX with that shader too.

Whilst I am sure you know what I mean by "black artifacts with bump mapping glass shader" objects issue, I have attached the two images which highlights the significantly better image generated with multiscatter which clearly does not suffer from the artifacts.
It doesn't crash with GGX.

Not sure if I uploaded that file correctly - let me know if there is a problem

I was having this problem this week.
I knew my scene was not using all my graphics memory (GTX970) but blender kept failing wih cuCtxSynchronize (I think it was that and not initialize) or sometimes blender was crashing altogether.
