I was messing arround trying to customize my desktop and i followed a guide on how to install and setup latte-dock (kde). Long story short, i failed removed latte (although I think it may have left some stuff behind) and when I restored my cinnamon panel the icon was like this. I've already restored the system with timeshift but it made no difference and tried to set "symbolic icon size" in panel settings but it completely ignores it. I googled for a solution but cant find any :c

Any ideas?

P.S. If I set panel height too small, all the applet icons go halfway off screen through the bottom, something they didnt used to do.

SOLVED: Using this comand:

gsettings reset-recursively org.cinnamon

Reverts the icons to their normal behaviour. Thanks to potatoguy
