So, is this a problem with the clip fullscreen window option? Or maybe because we also clip fullscreen windows when they are on a single monitor, like I described in https://gitlab.winehq.org/wine/wine/-/merge_requests/3076?

I'm not sure to understand how cursor clipping is causing issues with window creation. Even if the cursor is clipped and the clipping window receives all the input, we should still dispatch it to the right window after that?
