After resuming from suspend unity feels like it is very slow.
How to play:
Go to Unity Dash, show all applications, move icons up and down with the
scroll bar, suspend and resume, perform the same operation and notice
that is very slow.
This already happens with the (cd or usb) of installation.
This bug only happens with free radeon driver with driver fglrx does not
happen.
This only happens in unity, this does not happen in either Gnome Shell
or Unity 2D.
I do not know if it's a bug in Unity or compiz, but "unity --reset"
solves the problem until the next suspend / resume.
I do not know if this bug may be related to #782810 or #803943, but I
did not notice any increase in CPU consumption.
This bug occurs on a clean install of 11.10 [64 bits] with a ATI
Radeon 5770 graphics card, Asus P6T Deluxe V2 Motherboard, Micro Intel
Core™ i7-950 y SSD OCZ Vertex2.
