Bug ID: 57698
           Summary: Reason's (DAW) dialog windows stopped registering
                    mouse events and open at screen's right edge
           Product: Wine
           Version: 10.0-rc6
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: minor
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Reason's (DAW) dialog windows like "Save changes to the document before
quitting?" or the authorization/login startup dialog stopped registering mouse
click events with Wine v10.0-rc6. Additionally, affected dialog windows now
open at the screen's right edge instead of the center (on Windows and up to
Wine v10.0-rc5).

Additionally, the authorization/login startup dialog hides the mouse cursor
once the cursor is over its window.

There's a workaround though: you can move the window to the screen's center and
from that point on are able to move the mouse cursor within the window and
perform mouse clicks.

The regression has been introduced with commit
710b94e212501727b3b1b8deea06a7757df43d51

Steps to reproduce:
Follow the download and installation steps from "Additional Comments" here:
https://appdb.winehq.org/objectManager.php?sClass=version&iId=42495

Then, just wait for the authorization/login startup window.
