Steam - Windows Bug with special cancels maybe?

[Stuff]

So I'm not sure if this is a bug but I seem to notice that in some timings you just don't get a special cancel at all? My first thought is that hitstop makes the inputs a little murky that's kind of unavoidable I think (but I wouldn't really know). It's strange because even though the special cancel doesn't happen, the next button in the chain definitely does. I'm fly canceling with MK and you can see/hear pw go into its start up so I'm not sure if this is a bug or not. My inputs are generally the same, I just change a few timings here and there, I'm not sure what's going on so I thought I'd report it just in case.
