I have exactly the same issue on my desktop with GTX 1050 Ti. Klaus, do you
have any progress resolving it or some workaround?

I should note that I have one PC where qmlsink works without any visual
artifacts - Microsoft Surface 6 with Intel Core i5-8250U (Intel UHD Graphics
It seems it's still a graphics driver issue.
