I’m having the same problem on 1.21.5 - mostly affects text, some other textures like the azure bluet, beacon beams and bedrock, mobs can be completely green or black when damaged. The glitched textures change over time - text begins missing certain elements, then gains black pixels then coloured pixels. Sometimes items inside inventories flash, sometimes triangular sections of the whole screen. Interacting with inventories appears to speed up the corruption of textures. F3+T resets the glitched textures temporarily. As others have reported this is with Intel integrated graphics - my drivers are up to date.
