Nvidia user on a different distro. For me this also happens after just logging in; I don’t have to run a game first. All animation is very laggy/jerky (like the system is running at 5–10 fps). The easiest way to see this is to start the application menu (Kickoff) and select a tab. The glide animation when switching tabs is very jerky. Restarting kwin using kwin_x11 --replace & fixes this, and the animation becomes silky smooth. If I run a full-screen 3D game (e.g., Neverball), the animation becomes jerky again, and I have to restart kwin_x11 for things to become smooth.
