Bug ID: 49056
           Summary: Dragon Age: Origins right-click camera drag jumps
                    counter-clockwise on start
           Product: Wine-staging
           Version: 5.7
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]

Steps to reproduce:

1. build wine with staging --all, or staging user32-rawinput-mouse-experimental
user32-rawinput-nolegacy user32-rawinput-mouse.

2. open Dragon Age: Origins. start a new game or load a saved game.

3. right-click and move mouse to drag the camera

Expected results:

camera moves proportionally to mouse movement

Actual results:

as soon as mouse is moved (even 1 pixel), camera view jumps up and
counter-clockwise (as if mouse was instantly moved far right and up).
subsequent camera movement with the same drag is OK, but starting a new drag
causes the issue again.

doesn't seem to be related to the starting cursor location

Additional information:

occurs whether virtual desktop is on or off.
