WGPU 0.18.0 Not binding Texture Arrays in GL on windows.

[genusistimelord]

Description
In vulkan and DX12 the Textures arrays are bound successfully and They currently only have one layer as well. When attempting to test GL for windows everything but the texture arrays bind successfully. You can find the Demo used to test this here: https://github.com/AscendingCreations/render_demo

Here is the RenderDocs file
glcap.zip

here is a screenshot of it showing the textures not being bound.

Expected vs observed behavior
Expected the texture to be bound and used. Also expected the limit of arrays to throw an exception if the texture array got to large to not work with the adapter.

Platform
Windows 11
Nividia Geforce GTX 950
WGPU 0.18.0

Does it work if you force it start with 2 layers?

yes it does work if I force it to start with 2 layers.

This is most likely due to

wgpu/wgpu-hal/src/gles/mod.rs

Lines 358 to 364 in 2e7fd75

	// HACK: detect a cube map; forces cube compatible textures to be cube textures
	match (desc.is_cube_compatible(), desc.size.depth_or_array_layers) {
	(false, 1) => glow::TEXTURE_2D,
	(false, _) => glow::TEXTURE_2D_ARRAY,
	(true, 6) => glow::TEXTURE_CUBE_MAP,
	(true, _) => glow::TEXTURE_CUBE_MAP_ARRAY,
	}

This will be addressed once we add textureBindingViewDimension to the texture descriptor.

See WIP Proposal Doc & gpuweb/gpuweb#4266.

ahh ok for now setting it to multiple layers will fix the issue till you get this fixed on the backend.
