Toolbar In Yosemite Becomes Fuzzy After Mac Has Been On Awhile


Since updating to Yosemite, has anyone else noticed the tool/menubar and system menus on Macs / iMacs losing "focus" a few hours after starting up? I notice this in all Rt-click menus as well as the menubar. Fonts appear blurred instead of sharp. This isn't evident in the main windows of Safari but I do see it in Mail. I therefore assume it's not my eyesight. Hope someone can help.

My Mac is a 2007 iMac.
