midagedev/mwoyeo is a real-time screen translation tool that places a lens on the macOS screen and shows the text beneath it in your own language. It overlays the translated text right where it sits on the screen, and the processing happens on-device. v1.0.4, released on October 15, 2026, changed the rendering so that the rotating lens ring stops, staying still while only its brightness breathes softly. The source of the content is the v1.0.4 release notes on GitHub.
The starting point for this change was the cost of drawing the lens. The release notes state that redrawing the rotating gradient on every display frame had occupied about 60% of a CPU core per idle lens and was also a cause of stutter when turning the lens off. An idle lens means one that stays on the screen without being used. While the ring was spinning, the image to draw kept changing, and now only the brightness of the still ring rises and falls. In v1.0.4 macOS itself handles the lens movement, so the motion became smoother, and the glow changes softly while reading and translating. This repository has 51 stars.
The 60% figure is a value cited by the release notes, not a re-measured result from outside this repository. The license is not specified in the release materials. The scope described by this version covers only rendering behavior, so there is no basis to read it as a change in translation accuracy or recognition performance. v1.0.4 is not a release that broadens features but a conservative improvement aimed at reducing the load of translating the screen, and the extent of the improvement does not go beyond the scope the notes state.
