You should not use ffdshow. It uses a trick to merge the subtitles with the video. This results in artifacts because video frames are used as reference for later frames. This trick is needed for DXVA (native) to display subtitles in WMP.

You should instead use LAV Video decoder with DXVA2 (copy-back). That does not have any limitations with regard to subtitles and it should play without artifacts.

Can you post this info? Then I can check why ffdshow was (possibly wrongly) given as an option to you.
