GPU-AV: Indirect draw parameters are broken.

[corporateshark]

Environment:

• OS: Windows 10 64-bit
• GPU and driver version: RTX 3070 Ti, 561.09
• SDK or header version if building from repo: 1.3.290.0
• Options enabled (synchronization, best practices, etc.): GPU-Assisted - Buffer content validation - Indirect draw parameters

Describe the Issue

Run 3D-Graphics-Rendering-Cookbook-Second-Edition/Chapter08/03_LargeScene.

Expected behavior

Disable Indirect draw parameters.

Valid Usage ID

No validation messages.

P.S. There's no issue in Vulkan SDK 1.3.268.

It seems related to the long time issue we've had of not resetting disturbed pipeline states. We know from the Vulkan face to face that we need to rethink how we do things, so a fix will unfortunately not be ready by next SDK...

[spencer-lunarg]

As @arno-lunarg said, we have found the original idea/way for command validation (things like checking the indirect draws) has a lot of flaws once we started to actually add support for things outside basic Vulkan 1.0 concepts in the last few months.

We have a redesign mocked up and for the short time being, we will likely turn that setting off by default for the next SDK.
