[22:04] 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] [Ubuntu 15.04 64-bit, i7-2700k CPU, 16GB DDR3, Dual GeForce GTX 760 /w nvidia-346 proprietary drivers] [22:04] 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] 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).
