Under Proton-based Wine, `tabtip.exe` is a UI Automation client, and `bevy_winit` gives every window an AccessKit provider. That traffic faults in `rpcrt4` on blocks the game has reused, which damages the heap and later crashes the client at varying addresses. Blocking `tabtip.exe` stops the faults and the crash, and other programs in the same bottle show no such faults.
The reference's window has no provider: `WoW.exe` imports no accessibility library and names none of its calls. benilla builds no AccessKit tree either.
`VideoPlugin` now drops the adapter when Windows reports a new window, which restores winit's window procedure. Other platforms keep theirs.
No test: the adapter needs a real window and the fault a UI Automation client. Built for macOS and Windows.
