My Kingdom for Smooth ABS SA Keycaps
Every time I build a new keyboard, I go hunting for keycaps. And every time I go hunting, it eventually devolves into a desperate search for SA (or equivalent) profile keycaps with a smooth finish. SA is the ultimate profile, IMHO, and they're relatively hard to come by. Signature Plastics, which is where a lot of SA sets come from like the T0mb3ry SA Carbon set (they might actually hold the trademark on the SA profile if I'm not mistaken), is reportedly going through some management/ownership struggles (last I heard, they're looking for new ownership), and along with apparently the rest of the industry, they seem to be neglecting this superior keycap profile in their own stocks. If you order direct from them, they have a couple themed sets in stock (maybe), but generally you can have any color you want, as long as it's black or white. Drop carries a fair number of MT3 profile sets, which are very similar to SA. But just like SP's SA-P profile, they're made with a different...

If you scroll down someone posted a pic of how to fix the issue.
This page has a clearer definition: (https://elitekeyboards.com/switchhitter.php)
"Key switch "chattering" aka "contact bouncing" is a natural occurrence in mechanical switches that can cause one switch press to be detected as multiple presses. Digital electronics in a keyboard normally filter out chatter and can handle a small deviation in chatter in a properly performing key switch, however, in the case that a switch is damaged or defective, the amount of chatter can become too large to be filtered. The result is a repetition of key input seen on your computer screen for only one intended key press.
For a typical Cherry MX based keyboard, the chatter filtering is set to 5-10 milliseconds, but this is not a value that is typically disclosed by keyboard manufacturers. Since input speed capability is a marketable specification, many manufacturers understandably push their luck in this regard. This means that switches must be of excellent performing condition in order to avoid chattering. Unfortunately, environmental contaminants and keyboard build quality can affect how quickly a key switch departs from an acceptable chattering range, and most Cherry MX keyboard owners will see some chattering at some time in their keyboard's lifetime. Fortunately, the amount of chattering is often not frequent enough to cause noticeable issues for most users. However, if you think you may have a chattering issue, Switch Hitter can help diagnose just how bad it is and whether a repair is justifiable."
