I'm having a weird issue, I don't know what's causing it, but every now and again the icons in my menu bar switch to the non-retina assets, so my better touch tool, wifi, bluetooth, volume, battery, time, etc switch to the blurry icons of non-retina assets. The thing is, the apple and all the text for the current app are all retina assets, and killing the menu UI from the terminal and letting it restart solves it but I'd like to know what will solve it for good, any suggestions?
