I have to assume this is on myspleen. Since apparently there's no way to get access there for us mere mortals (hint: help a brother out!) I could only locate and download "The.Matrix.Restored.Theatrical.Colors.Edition.1999.720p.BDRip.MULTIAUDIO.x264.DTS.AC3.Shadoe" which is a re-encode.
My observation is almost every time there's a "flash" (lighting, gunfire etc) that there are artifacts.
