i'v already reported these bugs to apple, here: http://www.apple.com/feedback/macosx.html but i wanted to know if its a problem on all macs or just some - the new 3D dock makes desktop space switching laggy, and it only returns to full lion-like smoothness when in Hidden mode, or in 2D dock mode on the left or right. the other problem its caused is it makes LaunchPad icons slightly blurry, if you use the 2D dock on left or right, the LaunchPad icons return to full sharpness. then lastly, if i have the Dock in 2D mode on left or right position, there is then a laggyness and lack of smoothness in swiping the first 2 pages of my LaunchPad apps, only returns to smoothness when the 3D dock is back at the bottom! sigh, i hope this is fixed soon. amongst other ones i'v experienced: Freezes that result in hard resets. colour profile switching when graphics switches to discrete.
