On Debian 13 KDE, when hovering over window previews in the app drawer, I get huge drops in FPS and laggy experience. Anyone else experiencing this or has a clue what could be done about it? I'd prefer an actual solution, not workarounds like disabling previews or turning on 1 app = 1 window. Video of the behaviour: https://youtu.be/9XnNLWPWZcs

The FPS drop begins as soon as mouse leave the app icon and persists over the duration of staying on the preview panels. Notice how mouse sticks to borders for a bit then has huge jumps, it's even worse in real life than on video. Even though the FPS counter shows drops from 400 to 200, it feels like sub 30 fps.
