That's to be expected. The 2D acceleration is very good for small updates (like adding a character in your terminal or redrawing the clock in your statusbar) and 3D acceleration is good for big updates like moving windows. I use a tiling WM that arranges the windows automatically and don't normally move them so I see this issue only when testing. Also it is not clear that the packaged fbturbo version supports any kind of hardware acceleration on the Raspberry Pi and even that there is any kind of acceleration to support. Still the shadowfb software acceleration is very good. Of the actual 3D drivers only Intel comes close to its performance AFAIK.
