I tried the latest Vulkan driver with the latest Dota 2 for Vulkan and it tries to start, but immediately crashes:

While the Vulkan driver is probably doing something wrong, the DRI driver shouldn't crash either way, should it?

A hang is not a crash.  In any case, I'll pull the latest Dota 2 and take a look on Monday.

I just pushed some commits to master that should fix this.  Re-open if you still get hangs.
