Comment 6 for bug 1058388

I think I am experiencing the same issues. When I use Remmina (remote desktop) or VMWare player, and try to move windows to another screen or workspace, they jump to seemingly random screens.
After some clicking and moving around, I often get the window on the screen I want, but if I switch applications, things get funny again. I try to prevent my colleagues from seeing this; it's embarrassing.
I have been using Mac OSX until recently. I have never seen such good support for multiple monitors. Let's hope Ubuntu gets the same quality. Let's hope this bug gets higher priority. More and more people use multiple monitors.
