Hi. I'm running OS X 10.7.4 on a 15" MBP from 2010 (nvidia 330m, i5), and often times I'll notice my menubar at the top has some strange graphical glitches. Sometimes the entire bar will be clear and sometimes it will have overlapping glitches on the text. I've attached 2 examples of how it looks, but it does other, similar things. Sometimes it's much worse. I've removed the systemuiserver plist and done "killall SystemUIServer" and rebooted, but it persists. My non-default menubar items consist of: last.fm, dropbox, google notifier, smcfancontrol, menumeters. Any ideas would be appreciated.
