After using Ubuntu 11.04 for a while, on different PCs (desktop, netbook), I noticed some unexpected behaviours (slowdowns, crashes, screen garbage). This most likely is a problem of proprietary drivers (nVidia, ATI/Radeon) and Compiz (the 3D compositing window manager).
The solution, although not the most popular, is simple: when you log in, select Ubuntu Classic (no effects), and you'll have a fast, responsive and stable Ubuntu Linux system. I'm not fussed about losing the eye candy, and have no problem waiting for the next release (11.10), anyway.

Thanks to Andrew from Web Upd8, here's a way to disable Ubuntu 11.04's weird scrollbars and revert to the "old" ones. It's a terminal hack, so you need to open it and type the two lines below to make it work. You may or may not have to restart your computer to finalise the changes.
echo "export LIBOVERLAY_SCROLLBAR=0" > /etc/X11/Xsession.d/80overlayscrollbars
