Has anyone else experienced this? It seems to be a very weird and annoying bug. And I've been seeing this since I installed Yosemite last year. Here you have some evidence of what I mean: Also notice: - This bug also includes weird black lines between the menu bar icons. (Originally they looked worse, but as I took the second screenshot they disappeared, except for the very tiny one that is between the users icon and Spotlight.) - It doesn't seem to have nothing to do with the LCD font smoothing option (tried disabled and re-enabling it). Text in general and other elements on the screen look fine. It's only icons and text in the menu bar that turn blurry... and sometimes some 'specific' pieces of text on the screen. - It happens randomly. Most of the time my menu bar looks fine. But pretty often it will get blurry out of nowhere. Seriously, wth Apple?
