Bug ID: 51533
           Summary: Some Radeon driver versions seem to break
                    kernelbase:sync
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: kernel32
          Assignee: wine-bugs@winehq.org

Call timeBeginPeriod(2) to reproduce the bug
Some Radeon driver versions seem to break kernelbase:sync:
https://test.winehq.org/data/patterns.html#kernelbase:sync
sync.c:197: Test failed: got 0.203642
This failure only happens on cw-rx460, specifically:
* cw-rx460-1909 which has 21.5.2
* And it appeared on cw-rx460-1809 on 2021-06-25 which is when that version was
switched from the 19.9.3 Radeon driver to 21.5.2.
As a counter-point it happened once on cw-rx460-1709 (2021-06-18) when it was
switched from 19.11.3 to 21.3.2, but it has not happened since despite that
configuration still running the Radeon 21.3.2 driver. So maybe there is some
other issue.
In fact the test behaves exactly as if some application (e.g. some Radeon
driver component / GUI) called timeBeginPeriod(2), since that impacts all
running applications before Windows 10 2004.
