Version: (using Devel) OS: Linux Installed from: Compiled sources I'm using Arch Linux Kdemod unstable 4.1.87 snapshot, with NVIDIA 180.18 driver on a GeForce 7600 GS graphic card. Compositing is on. Windows resizing using the Ozone or Oxygen kwin decoration is extremely slow and unresponsive. On the same system using the QtCurve or Plastik (or whatever isn't Ozone or Oxygen) window decoration the resize operation is very fast and absolutely in realtime.
