Blank Icon Appears in Status Menu Bar in El Capitan
At what seems like random times, the Menu Bar icons for the Status Menus (near the clock) shift to the left for a fraction of a second.
I tried disabling 3rd Party icons, but have not found a solution. I recorded a screen capture, and took stills from that to figure out which icon was causing the problem. The latest observation is that the jumping icons seems to occur between Apple's stock status menu icons (beginning with bluetooth icon) and the 3rd Party icons (iStat Menus, etc).
I have a clean-install of El Capitan on my Mac Pro and MacBook Pro, and both seem to do it, randomly (FYI MBP doesn't run iStat Menus, but does run the others: 1Password, ClamXav Sentry, & Little Snitch).
Anyone else having this happen or know why?
Thanks.
