X11DRV_ThreadDetach() destroys thread data part of which (e. g., display) is still present in window data in winex11.drv and accessible through hwnd. That causes all sort of hangs and crashes when, for instance, the window is still used for Vulkan rendering (even if only to tear down the device and swapchain).
