The article discusses the performance criticism of immediate-mode UI frameworks, where the interface is rebuilt every frame even when unchanged. The author presents a caching approach that attaches a cache to the rendering side, allowing the UI to describe itself fully each frame while only re-rendering changed portions, balancing simplicity with energy efficiency on battery-powered devices.
Background
Immediate-mode UI frameworks like Dear ImGui are popular for their simplicity but criticized for redundant per-frame reconstruction. Blick is an open-source video editing application built with such a paradigm.
