Attempted to use the same texture in framebuffer attachment error

[UltraWelfare]

Godot version:
v4.0.dev.custom_build.2c0d1c3b9

OS/device including version:
OS: EndeavourOS (5.9.13-zen1-1-zen)
GPU: Intel UHD 620 (with integrated: Radeon 530)
Backend: X11 / Vulkan

Issue description:
Upon opening any new project (either creating one or loading one), the Output tab (and the terminal, if launching godot from there) continuously shows this message:
ERROR: Attempted to use the same texture in framebuffer attachment and a uniform set, this is not allowed.

The terminal outputs an extra line:
at: draw_list_bind_uniform_set (drivers/vulkan/rendering_device_vulkan.cpp:6176)

Steps to reproduce:

1. Create a new project.
2. Look at the output tab (or the terminal)

Minimal reproduction project:
Not needed as it happens with the creation of any new project.

I spent some time tracking this down tonight, but haven't gotten anywhere yet. I'm recording notes below to help myself later or someone else.

The issue stems from binding the depth and normal textures for reading during any of the three main passes (prepass, opaque, alpha).

All three passes share the same uniform set which is declared here

godot/servers/rendering/renderer_rd/renderer_scene_render_forward.cpp

Line 1841 in 5332d21

RID rp_uniform_set = _setup_render_pass_uniform_set(p_render_buffer, radiance_texture, p_shadow_atlas, p_reflection_atlas, p_gi_probe_cull_result, p_gi_probe_cull_count);

Specifically it comes from binding the depth and normal_roughness textures in _setup_render_pass_uniform_set:

godot/servers/rendering/renderer_rd/renderer_scene_render_forward.cpp

Line 2426 in 5332d21

RID RendererSceneRenderForward::_setup_render_pass_uniform_set(RID p_render_buffers, RID p_radiance_texture, RID p_shadow_atlas, RID p_reflection_atlas, RID *p_gi_probe_cull_result, int p_gi_probe_cull_count) {

godot/servers/rendering/renderer_rd/renderer_scene_render_forward.cpp

Lines 2503 to 2510 in 5332d21

	{
	RD::Uniform u;
	u.binding = 4;
	u.uniform_type = RD::UNIFORM_TYPE_TEXTURE;
	RID texture = rb && rb->depth.is_valid() ? rb->depth : storage->texture_rd_get_default(RendererStorageRD::DEFAULT_RD_TEXTURE_WHITE);
	u.ids.push_back(texture);
	uniforms.push_back(u);
	}

godot/servers/rendering/renderer_rd/renderer_scene_render_forward.cpp

Lines 2521 to 2528 in 5332d21

	{
	RD::Uniform u;
	u.binding = 6;
	u.uniform_type = RD::UNIFORM_TYPE_TEXTURE;
	RID texture = rb && rb->normal_roughness_buffer.is_valid() ? rb->normal_roughness_buffer : storage->texture_rd_get_default(RendererStorageRD::DEFAULT_RD_TEXTURE_NORMAL);
	u.ids.push_back(texture);
	uniforms.push_back(u);
	}

The depth prepass binds the depth and the normal_roughness textures as framebuffers, so the issue makes sense. But the error occurs on the opaque and alpha pass as well. It is on this point that I need to investigate further.

Just a data point over here: the error, still spammed, now says

ERROR: Attempted to use the same texture in framebuffer attachment and a uniform (set: 1, binding: 6), this is not allowed.
   at: (drivers\vulkan\rendering_device_vulkan.cpp:6183)

@Calinou #44523 seems completely unrelated, so feel free to keep this closed

[akien-mga]

@reduz Read again, there's still very closely related error spam: #44473 (comment)

when i apply the texture, that a SubViewport outputs as the texture of a Sprite2d, it spams an error in the debugger:
draw_list_bind_uniform_set: Attempted to use the same texture in framebuffer attachment and a uniform (set: 3, binding: 0), this is not allowed.

Yes, that isn't allowed. You can't read from the texture that you are writing to
