https://pastebin.com/yCynk3hP Here is an strace of a simple vulkan app
https://github.com/cheako/cheako-vulkan/blob/v0.1/0002lighting/vulkan.c that
locksup the X11 desktop.

It may be useful to note that 0001uniform-buffer-object and 0003index-buffer do
not lockup.

There are a number of other issues with these example applications and I'll
open other bugs for those.
