GPU Freeze if vkQueueSubmit contains no command buffers

[thynnmas]

Hi,

Unless I am misreading the spec, vkQueueSubmit may contain no queues (submitCount of 0), which in combination with a fence & can be used implicit synchronization gruanatees can be useful in some cases.

In the latest versino of RGP, if a submit contains no command buffer, the following behavior is observed:

1. The application crashes in vkQueueSubmit in the amd driver.
2. RGP's connection times out and it shows an error that profiling failed.
3. The computer's display freezes, and does not recover. A hard reset is required.

Submitting a single empty command-buffer works around the issue.

I've attached a small repro (adapted from this) which has an extra entirely empty submit. The issues reproduces with this program for my by running it with RDP open, and triggering a capture.

This should be resolved in recent drivers. If you still see this issue with recent Adrenalin drivers, please let us know
