It uses a hack to get the whole window from Wine, using GetPropA(g_host.hwnd, "__wine_x11_whole_window"); and then the plugin calls XReparentWindow on it. This messes it up on the Wine side because root_window is not updated when that happens so it becomes out of sync with Wine's expectations.
This is bypassing the normal windows behaviour and there isn't anything we can do to fix it. Marking as NOTOURBUG.
Reporting the bug upstream could help.
