           Summary: Regression Requiem: Rise of the Reaver mouse issue
                    since Release v5.0-rc3
           Product: Wine-staging
           Version: 5.0-rc3
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: -unknown

      Distribution: ---

radeon/amdgpu (same behaviour)
X11 on openbox

Game:
Requiem: Rise of the Reaver (http://www.playrequiem.com/)

Use case:
windowed multi client (transfer of items, shop open in the background etc.)

issues:
- need to click once to activate the game window and then it operates normally,
before it was a direct click through (activate game window and action in the
game)
- mouse cursor gets trapped in game window A while moving the mouse to game
window B and activating game window B (game window A/B overlapping a bit since
monitor resolution).

My issues started between Release v5.0-rc2 and Release v5.0-rc3 (update of the 
raw input patches?) and are still on going.
