Issues after switching to Radeon GPU

Newbie here, i tried switching from my Intel iGPU to my AMD Radeon (TM) R7 M340 with DRI_PRIME=1 and it worked, but it looks like a fresh Windows installation with no GPU driver installed, i tried switching back to the Intel iGPU and i got the same thing, (I'm using KDE Plasma) the Titlebars are not round anymore, no animations, and no blur effect, also when i try to watch a video on youtube it's not as good as before, i can't play games without intense stuttering, the system overall is not fluid.

$ DRI_PRIME=1 glxinfo | grep "OpenGL renderer"
OpenGL renderer string: AMD Radeon (TM) R7 M340 (ICELAND, DRM 3.40.0, 5.10.56-1-lts, LLVM 12.0.1)
