Using too much VRAM on Linux crashes Editor
Behaviour: When UE4 runs low on VRAM when running in Vulkan (now the default on Linux), the editor crashes.
Expected: When the editor runs low on VRAM, it takes some kind of steps to reduce VRAM usage (In OpenGL it appears to drop the framerate, but I'm not sure what happens exactly behind-the-scenes).
Notable error line:
My setup that probably contributes to the issue: Antergos Linux (Arch)

Found the solution in another thread.
$ ./Engine/Binaries/Linux/UE4Editor -opengl4
Although it is mentioned in the documentation, the problem is not obvious.
