Loading normal map from JPEG file (yuv420p) via FreeImage leads to severe blocking artifacts in RGB24 result. JPEG_ACCURATE loading flag doesn't improve quality.

At the same time, loading the image via FFmpeg and converting it to RGB via swscale with accurate flags SWS_ACCURATE_RND|SWS_FULL_CHR_H_INT produces good result.
