Visual regression in DRAW_COLOR_CANDLES rendering (Blend2D Anti-Aliasing artifacts)

New comment
 
Hello,

I would like to report a rendering issue regarding DRAW_COLOR_CANDLES that has persisted since the introduction of the Blend2D engine.

The Issue:

The anti-aliasing algorithm applied by the new engine seems to render pixels outside the strict geometry of the candles to smooth the edges. While this works well for curves, for dense rectangular objects like candles, it artificially increases the width of each candle by 1-2 pixels.


This "pixel bleeding" causes adjacent candles to visually merge into each other, especially on standard or lower zoom levels.


Is there a plan to adjust the anti-aliasing threshold for candle drawing styles, or an option to disable AA for specific drawing buffers?
