I bought a used Laowa 10mm f2 but only used it on one outing before I sold it. Even though I had a GX7 and GM5 at the time but, I only used it on my GX9. For me, 10mm was much wider than I expected and decided I preferred my Olympus 12mm f2. That was my only reason for selling it. I agree with most of what you said but I really didn't see the vignetting you did. I rarely use hoods and left the 10mm's hood in the box. Also I put a brand new Hoya NxT Plus 46mm UV filter on as soon as I got the lens.

Portrait angle and right on top of those trees

The shot above is at f2.0 (others at f8.0) and looks good. Did you have in camera "shading compensation" vignetting control switched on or did you correct vignetting in processing?

Until you  just told me about the "shading composition", I didn't know it existed. I just checked my GX9 and it's set to Off and would have been the same when I took those shots. I didn't see any vignetting and so did not need to correct any in post. Also I stopped shoot raw and only shoot jpegs for the past two or three years. Based on what I was doing at the time, Photo Style would have either set to Standard or Natural.

If I understood the OP correctly, the vignetting is caused by using a filter or the hood. No hood, and the 46mm Hoya NxT Plus UV filter I had on the lens has a thin ring designed to prevent vignetting with ultra-wide lenses.
