Bug ID: 52984
           Summary: d3d8:device - test_cursor_pos() missing a MOUSEMOVE on
                    cw-gtx560 and cw-rx460
           Product: Wine
           Version: unspecified
          Hardware: x86-64
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: directx-d3d
          Assignee: [e-mail]
          Reporter: [e-mail]

d3d8:device - test_cursor_pos() is missing a MOUSEMOVE most of the time on
cw-gtx560 and cw-rx460:

device.c:1324: Test failed: Didn't receive MOUSEMOVE 0 (50, 50).

This happens almost systematically on cw-gtx560 and cw-rx460 with Windows 10
1709 to 1909 but happens much less frequently with more recent Windows
versions.
Also it never happens in the TestBot VMs running the same Windows versions and
also does not happen on fgtb-w10pro64-rx550.

So it may be related to the set of display modes that the monitor supports
which would explain why the KVM-connected machines are impacted and not the
others.

Or it could be related to the GPU drivers and fgtb-w10pro64-rx550 just got
lucky because it's on a more recent Windows version.
