[Bug 803296] Re: Normal resize with the new compiz is slow


In my case there it's not slow: it doesn't work at all with some applications, it works normally with others.
The ones that don't resize are Firefox, Nautilus, evince, Thunderbird and Compiz Configuration Settings. To complete a resize I have to release the mouse button, only then the window resizes itself.
The applications that resize following the motion of my pointer are Terminal, Libreoffice (when I manage to grab its resize handle) and VirtualBox.
I didn't try other programs as I just updated from 10.10. I only tried Ubuntu Classic.
I'm using an ATI X1600 Mobility card. From my dmesg file:

Setting the resize mode to stretch works for all applications but the inability to smoothly resize Firefox with mode Normal really affects web development so I'm considering to revert to the previous compiz as explained in http://www.webupd8.org/2011/05/how-to-downgrade-to-compiz-086-in.html
