Let's Disable the "Jack Russell Terrier Launch Feedback". This is what I call the annoying bouncing icons that follows the mouse when opening applications.

The "bouncy icon" has been the default since 2003 and maybe it made sense back (I doubt it) but at this time I think it is just tacky.

In an ideal world, this would be replaced by a clean animation for every application launched but even though the icon exists in Plasma's iconset they never made a way to implement it. So I reluctantly suggest doing a static icon instead because it still lets someone know something is happening because there is an icon on their mouse/cursor but in a subtle way rather than an annoying "look at me" way.

Here is a video I made to demonstrate what I mean by the "Jack Russell Terrier Icons": https://youtu.be/4E1uePkqwrE?t=230
