Setting BGFX debug to BGFX_DEBUG_STATS on Init breaks rendering on Vulkan

[Sumethh]

With the Cubes example setting m_debug to BGFX_DEBUG_STATS on ExampleCubes::Init causes the rendering of the cubes to break on vulkan, this works fine on other backends (D3D11 / D3D12).

To reproduce in example-01-cubes:
Change m_debug to initialize to BGFX_DEBUG_STATS

Start the example up with the vulkan backend and the example rendering breaks:

For reference this is the example running in D3D12 with the same changes:

Hello. Are there any updates on this? I'm running into the same issue. I'm able to render a triangle successfully using "bgfx::RendererType::Vulkan;", but once I add "bgfx::setDebug(BGFX_DEBUG_STATS);" the triangle is no longer rendered.

I can take a look at this on Monday. I was unaware of this issue, but it seems like a simple bug.

@DarthCloud64 Just to be sure, did you use the latest version of bgfx? In particular, after I fixed #3418 in #3419? On my machine, the cubes don't disappear; but the debug text appears with a little delay after resizing the window, but that happens on other backends too. However, #3419 is a really relevant code fix regarding this issue.

@Sumethh can you try again with latest bgfx? Your issue dates from before #3419 was merged.

Good question. I'm using bgfx.cmake , which seems to be only slightly behind the master branch of bgfx

Git submodules can be tricky. Go into the bgfx submodule and manually check on which commit you are. To this day, I'm still not sure when git actually pulls and updates submodules.

Fix #3344 (#3399)

So yeah. There is your answer. Your bgfx repo is half a year old. I fixed this exact issue on March 31st, which got merged April 2nd.

[DarthCloud64]

Thanks for catching that. I'll update the submodules and let you know what happens.

@DarthCloud64 What happened?

[DarthCloud64]

@mcourteaux Sorry for taking so long to get back to you (been busy on other projects). I updated my submodules this morning within bgfx.cmake, and now I can successfully use "bgfx::setDebug(BGFX_DEBUG_STATS);" and see my shape render! Thanks for the suggestion
