KDE effects and graphics are broken

I’ve been using manjaro for a few weeks, but after a system update, the desktop enviroment started acting weird. Firstly, none of my windows close by fading out, they just disappear. Secondly, when I drag a file on desktop, it leaves a trail of itself, like the desktop isn’t refreshing.

Edit: of course here are my specs

Start with this:

I have edited my post, the only thing I cannot do is attach an image

actually i have fixed the issue now, by setting the opengl version in the compositor from 2 to 3.1, but another question arises: why does opengl 2 not work?

Probably because of mesa/amdgpu/kernel update … couldnt say for sure.
But 3.1 is better anyways so theres nothing to fret about.
