I think I may have found the same bug, albeit I seem to be causing it differently. I'm running Kubuntu 6.06, and frequently use KRDC to launch rdesktop to various Win boxes at work. I typically run my sessions in 1024x768, which is the full res of my laptop. If I leave the rdc screen maximized and leave my focus in it and let it idle, my mouse totally disappears from both rdc as well as KDE proper. What I have been doing is ctrl-atl-f1, log in console, killall -15 rdesktop, ctrl-atl-f7 back to KDE and log out as clean as possible with keyboard shortcuts. I basically have to restart X though to get my mouse back, just as the original author of this bug.
