Hello,
I am currently experiencing a problem with my X-T3.
When I use the mechanical shutter with high shutter speeds (1/5000s - 1/8000s), the image shows a darkening on the top part. This does not occur at shutter speeds below 1/1000s.
I don't have this problem when using the electronic shutter.
My tests below
