Signed-off-by: Paul Gofman pgofman@codeweavers.com --- Supersedes 217240.
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 the window is still used for Vulkan rendering (even if only to tear down the device and swapchain).
Since it turns out like the issue is actually winex11 - Vulkan specific, the new version of the patch implements the clean up in the Vulkan side.
The introduced list of surfaces can potentially be reused later (maybe with some additions) for Vulkan child window rendering implementation.
