I have experienced this problem as well, with an Intel 965 graphics kit. I tried the mouse-polling fixes suggested here (I often use Logitech USB mouse), but they didn't seem to make much of a difference for me.
Today this issue had deteriorated my desktop to near-unusability. My uptime was 6 days under heavy use, lots of suspend/resume, so I checked the system monitor to see what was going on. I noticed what I thought was an anomaly: unity-panel-service used nearly 105 Mb RAM, well above the ~6ish it uses when it launches. This memory leak is documented elsewhere (#779185), but this is what's interesting: when I killed unity-panel-service from the console, it immediately restarted as expected...but the window dragging issue went away immediately. I wonder if anyone else can confirm this? There may be a connection between the memory leak and the behavior we're seeing here. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/764330 Title: Move window annoying slow with compiz To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/compiz/+bug/764330/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
