Swiftshader MacOS crash on swapchain creation #70

Open lnihlen opened 4 years ago

Offscreen render contexts seem to work fine, but there's a crash in swiftshader when trying to create the swapchain. Callstack looks like:

It looks like there's potentially some odd interaction with glfw, see all the moltenvk log chatter in the above debug log.

lnihlen commented 4 years ago

It looks like glfw is assuming MoltenVK is the vulkan device of record when running on MacOS. Swiftshader breaks that assumption, and it's causing a crash somewhere within its internals.
