I can confirm the issue here on my Windows NVIDIA machine, but not my M1 Pro Mac. So there might be something with the GPU driver involved here. I tested in 4.3 and 3.6 and the issue was in both. I have also attached a python script to add a gizmo to the 3D viewport. It was adapted from this script by Julian Eisel.

Interestingly there was a report of a similar issue that could be seen on the built in gizmos. #118123
I can't reporduce this issue on the built in gizmos, but can on ones spawned by a script.

Hello, I have the problem both on windows and linux machines (OpenGL for linux, most probably OpenGL on windows)

Current machine used for the screenshot:

Worked: (newest version of Blender that worked as expected)

And it's worth noting that it also happens with custom shapes in gizmos.

In the setup method, you can create your own shape:
self.custom_shape = self.new_custom_shape('TRIS', list_of_vertices_coordinates])

Then in drawmethod call it as follows:
self.draw_custom_shape(self.custom_shape)

The little rectangle below the standard gizmos buttons is drawn with two triangles.
You can clearly see the diagonal in-between triangles when there is some geometry behind.
