I can confirm that.
I have the same problem with nVidia drivers (G72M [Quadro NVS 110M/GeForce Go 7300] on my Dell Latitude D620). With my 1GB ram I run out of memory in about 15 minutes! If I swap "Normal" visual effects to "None", memory usage will drop dramatically (from 90% to 40%). But when I switch visual effects back to normal, memory usage does not leap at all. If this is not a memory leak, then memory leaks do not exist.
