**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 [[ https://www.youtube.com/watch?v=8gSyEpt4-60 | 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.
