As mentioned on twitter I was able to get the editor to run (Godot Engine v4.0.dev.calinou.770a1d00a with debug symbols) by inserting a breakpoint with gdb at VulkanContext::command_begin_label:

break VulkanContext::command_begin_label

Then when it was hit first time, ran this:

set this->enabled_debug_utils = 0
disable 1
continue

The editor then ran without issue.

I was able to add a mesh, light & camera & then play the scene[0] (after the repeating the same steps for the new process).

From a quick look at the source history it seems this code was introduced in https://github.com/godotengine/godot/commit/7323cbab4bfcb5ad1fb0bd2dd667bdb450827335 (“Add named resources and debug labels in RenderDoc”).

Will investigate further…

After testing that the project ran okay, I then tested the more recent SDK setup with the editor (as there seems a difference between those two scenarios in general).

Running the editor via this command:

$ ./godot-v4-linux-nightly-debug-symbols-2021-10-06 --path /<path>/vulk-play-gg --editor

Resulted in quite a long pause but then the editor eventually opened.

Partial output included:

Godot Engine v4.0.dev.calinou.2e8cba0bd - https://godotengine.org

[...]

INTEL-MESA: warning: Haswell Vulkan support is incomplete

So, based on what I’ve observed, it seems that the issue does arise (at least in part) from not calling _get_preferred_validation_layers() which seems to do whatever initialisation is required: https://github.com/godotengine/godot/blob/77721b35ba21f2e7e8bb42cf415fccb018517843/drivers/vulkan/vulkan_context.cpp#L214-L264

It would be good to know why the equivalent of --vk-layers needs to be supplied in my case but not on other systems.

(Stab in the dark here, but could it be related to configuration of implicit layers: https://vulkan.lunarg.com/doc/view/1.2.189.0/linux/layer_configuration.html? Also, looking at that page suggests some possibilities for reducing the log spam which I might look into.)

Where to from here?

Potential future actions to take from here:

At a minimum it does seem like the functionality that’s causing the issue would be best to be behind debug-related command line switch because it’s not essential to game functionality. (Enhancement?)
Additionally, it would seem that the current code flow doesn’t ensure that whatever layer initialization is required is performed before use. (Bug?)
Finally, due to the amount of output from validation layers if the debug label functionality can be enabled separately from validation it seems like that may be a better default approach. (Enhancement?)
