Windows Vulkan driver advertises 16 sample anti aliasing but crashes when using it

The Intel Windows driver has the VK_SAMPLE_COUNT_16_BIT flag on image formats. When using it I get a hang and then vkQueueSubmit fails, probably indicating that the GPU hung.

This can be reproduced by enabling multi or supersampling in vkQuake 0.95 (https://github.com/Novum/vkQuake/releases/tag/0.95)

Workaround is to only use VK_SAMPLE_COUNT_8_BIT
