The broken spinners are fixed in the next build already, to be released soon.
You can disable the "scale out of existence" thing in the tyCache settings (there's an option for scaling on subframes when dead), however, that doesn't explain the subframes you're seeing if your keys are indeed linear.
The only "normal" cause for that is typical floating point errors that exist all throughout max (where 1.0 might display as .999999), which is just a regular floating point precision issue. But that shouldn't have a visible impact on playback.
Another thing: if you're just hitting "play" and your time configuration is set to "realtime", 3dsmax will playback subframes if it thinks it needs to. So what you're seeing in the viewport might not reflect what you'd actually see in the render. So maybe do a playblast and see if the artifacts are still visible.
