KDE system sluggish the longer it's up
Been using Slackware64 14.0 on a Lenovo W520 with an nVidia GPU and so far things have been pretty good except for the sluggish performance of KDE if I stay in KDE for more than a few days. Things get worse if I have VMWare running and even after closing it KDE still feels a bit slower than it should. This was with the stock KDE for 14.0, as well as with 4.10.2 from AlienBob. I'm just wondering if anyone else has been experiencing this. Using Xrender the system is a lot more sluggish than with OpenGL and things get back to normal once I restart KDE. Any suggestions?
