Smooth resizing of Qt 4 applications on Compiz

[rikhemsley]

Ah, I wondered what was up with resizing. Much better! I still see lag behind the cursor, though. Any idea what's causing that?

the lag is the drawback of supporting the NET_WM_SYNC_REQUEST protocol - since the window manager will delay resizing of the frame until the window is ready to be redrawn - basically the slower repaint, more lag you'll see.

However I think it should be up to the window manager to detect that repainting takes time and somehow prevent the lag, for example by showing a resize frame.
