Panics on Nvidia + Wayland

[dag-h]

When enabling the plugin on a system running Wayland with Nvidia graphics, the application panics:

thread '<unnamed>' panicked at 'wgpu error: Validation Error

Caused by:
    In a RenderPass
      note: encoder = `<CommandBuffer-(0, 2, Vulkan)>`

I'm assuming it has to do with this particular system configuration. Related:

I have the same issue and I had the issue with my own code as well. I fixed it by changing texture format:

            texture_descriptor: TextureDescriptor {
                label: None,
                size: ext,
                dimension: TextureDimension::D2,
                // 0.11.0
                // format: TextureFormat::Rgba8Unorm,
                format: TextureFormat::Rgba8UnormSrgb,
                mip_level_count: 1,
                sample_count: 1,
                usage:
                    TextureUsages::TEXTURE_BINDING |
                    TextureUsages::COPY_DST |
                    TextureUsages::RENDER_ATTACHMENT,
                view_formats: &[]
            },

could you elaborate what you changed and where? Do I need to change the bevy-inspector-egui source? Or ist the texture_descriptor somewhere in my source code (in some default or something).

This looks like the issue vladbat00/bevy_egui#192
I was able to fix it with that one line change in my own simple code, but not sure precisely what the fix would be with bevy_egui or if it is possible to make it work without changing the source code.
