Method GcCompactTransientWindowBuffers

lib/imgui/imgui.cpp:2738–2750

Free up/compact internal window buffers, we can use this when a window becomes unused. This is currently unused by the library, but you may call this yourself for easy GC. Not freed: - ImGuiWindow, ImGuiWindowSettings, Name - StateStorage, ColumnsStorage (may hold useful data) This should have no noticeable visual effect. When the window reappear however, expect new allocation/buffer growth/copy c
