[22:04] <m000gle> I've been experiencing performance issues with Ubuntu's Unity desktop environment, despite having a plenty powerful machine.  Could someone help determine whether this is normal, and/or troubleshoot?
[22:04] <m000gle> [Ubuntu 15.04 64-bit, i7-2700k CPU, 16GB DDR3, Dual GeForce GTX 760 /w nvidia-346 proprietary drivers]
[22:04] <m000gle> When changing focus from one window to another there is a split second, but very noticeable, lag between the mouse click and the focus changing.
[22:04] <m000gle> This appears to only affect changing focus between regular windows, and does NOT affect changing focus between two maximized windows (eg. one on each of the two monitors).
