+
+When a SDL_PollEvent is sandwiched between SDL_CreateWindow and
+SDL_CreateRenderer, SDL crashes during SDL_IME_PumpEvents because dbus message
+still references the old window (still exists and pointer is non-NULL) and
+tries to access members of window->driverdata (block was freed and pointer is
+NULL.)
+
+Workaround this by recreating the SDL_Window object and immediately afterwards
+creating the renderer.
+
+This crash only happens for gzdoom when running with the SoftPoly rasterizer,
+as that is the only place that issues SDL_CreateRenderer after the mainloop has
+started.
+
+Needs a bugreport on libsdl.org.
