Research direction

Start by reproducing the issue in Chrome with maptalks v1.0.0-rc.33, comparing the two attached images with terrain enabled. Trace the rendering path for Tianditu imagery annotations and identify where the visible aliasing and glow are introduced. Done means the annotations render without the reported artifacts in the same terrain scenario.
