Device Lost or (sometimes) extremely slow rendering.

Expected behavior

Valid Usage ID

No validation messages.

@spencer-lunarg If you plan to reproduce this with the latest version, please note that this validation check is now deliberately disabled in LVK as a workaround.

@corporateshark thanks (for reporting this providing samples for us to use)

I have found some other issues in traces that might be related

• update, might be fixed with gpuav: Fix Post Processing failing on zero bindingCount #9356

[corporateshark]

Just checked the new Vulkan SDK 1.4.304.1. Still negative function. Device lost.

[spencer-lunarg]

yes, the 1.4.304.1 SDK only had a 2 commit cherry-picked (we don't try adding to much drastic changes in a minor release), one for pointer crash and one to point the URL to a better/faster page to load the VU error message

I still think this might be fixed (haven't had time to repro yet) but known to not be in the 1.4.304.1 SDK
