Short description of error
I have had this issue since I started using 2.8x back in December. I've been trying to follow the Cycles optimisation tips by the Blender Guru in this video, but when I try to set the render tiles to 512 or 1024 with the GPU selected, Blender has consistently been crashing every time, especially right at the end of a completed render of some reason. Also, rendering on the CPU does not cause these crashes for me strangely.
Exact steps for others to reproduce the error
Set the render tiles to one of those numbers on a scene. I don't know what is causing the issue, but if it is a universal problem, Blender should crash eventually from rendering with those settings.
