I made also bugreport to AMD, maybe its their driver bug

I can't reproduce it on Linux with AMD Radeon RX Vega M (Mesa 19.3.4, kernel 5.5.6).

I saw that, but it's still relevant information that it can't be reproduced on Linux, and is therefore likely a Windows-specific issue. You reproducing it on Windows doesn't mean by itself that it's a Windows-only problem.

And even my test doesn't mean that it's Windows-specific. It could mean that it doesn't affect Vega M even though it affects Vega 8. Who knows... But to know, we have to test and document our test results, as I did. This may not be relevant to you but it is to developers who would try to reproduce and fix this issue.
