Transparency broken on Wayland. (Smearing)

[codecnotsupported]

Using Vulkan, attempting to render white squares I noticed smearing.

I tested this with KDE/Gnome/GLFW/winit git master with the same result.
Although if you pass a small(er) window resolution to GLFW and make a large(r) swapchain the window will be transparent for the part that isn't the window resolution.
Example:

Note that it will render just fine outside of the window resolution meaning transparency is supported, just broken-ish?

Closing for now as I cannot determine it be a winit specific issue. Will re-open if it is the case.

Confirmed a Winit issue.
Removing:

winit/src/platform_impl/linux/wayland/window/state.rs

Line 482 in 7929999

region.add(0, 0, i32::MAX, i32::MAX);

Causes the window to be always transparent.
