LCD Text Rendering – Algorithm, Heuristics & Scroll Raster Impacts

The source text provides an extensive technical overview of LCD text rendering (subpixel antialiasing) within the Google Chrome browser's architecture, involving the Blink rendering engine and the Skia graphics library. It details how LCD rendering exploits subpixel geometry to enhance text sharpness but introduces significant complexity regarding color alignment, which Skia manages using a "gamma hack" for correct blending. A major focus is placed on the numerous heuristics Chrome uses to enable or disable LCD text, such as requiring opaque backgrounds, integer transforms, and specific platform capabilities, to prevent color fringing artifacts. Furthermore, the document thoroughly explains the trade-off between text quality and performance when scrolling, noting that modern Chrome often prioritizes smooth composited scrolling by falling back to grayscale antialiasing over preserving crisp LCD text.
