I am new to Ubuntu and I like it.
I have some issues with the window movement performance (in Unity). My PC has a AMD Phenom X4 955 processor, 4 GB ram and AMD HD 6950 graphics card.
So its not that slow, but the windows (Nautilus, Firefox - just about any window really) move very sluggishly. I tried it with the AMD driver that Ubuntu provides (FGLRX driver, the standard, not the newest) and without it. I have installed Compiz Config and disabled the vsync, and also tried to switch vsync in the catalyst drivers on and off. Nothing seems to work.
Sometimes the window movement is perfectly smooth for a moment, then it gets slow as hell again. the other effects like minimizing are working very smooth. Any ideas what to do? It's really annoying.
