I've noticed this in several situations, especially on pretty low load, that Plasma suddenly starts staggering and lagging a lot.
When i use ALT+Tab to switch windows, its instant, but when i click on the app icon in the panel, it sometimes takes up to 10 seconds to react. When i kill plasma and restart it, it works fine, but it comes back from time to time.
Using an Ryzen 7 5700G with the OpenSource Radeon Driver. Do not have this issue in GNOME.
Anyone else experiencing something similar?

I noticed that, before this happens, KWin is causing quite some GPU usage. This is especially triggered when switching between light and dark mode as it seems
