FFmpeg's ass filter draw wrong shapes

I have an ass file with some specific shapes, when I use command line <ffmpeg.exe -v 9 -loglevel 99 -i "D:\test\1.mp4" -vf "ass=D
:test/1.ass" -f mp4 -y "D:\test\ffmpeg.mp4"> to burn it into video file, the shapes are in a mess. But when I use FFmpeg+AvisynthPlus (command line <ffmpeg.exe -i "D:\test\1.avs" -f mp4 -y "D:\test\ffmpeg+AvisynthPlus.mp4">) to burn it, the shapes are exact. All the files and logs are attached.

FFmpeg version: 3.3.2 64 bit
The OS version: Windows 10 64 bit
