I am also seeing this problem in the KDE spin of Fedora 22 (plasma-workspace.x86_64, v5.3.1-2). After using the system for a while (not sure on the amount of time), RAM usage is around 3-4 gigs with just the desktop and Konsole running.
Not sure if this is the same issue, but when the memory usage is high the desktop starts flickering when I select applications from the taskbar, and windows aren't rendered completely/correctly.
