Weird arrow icon next to Apple logo I am seeing this weird arrow icon next to Apple icon in OSX Mavericks. No idea what it is. The z-index is higher than the mouse pointer. (If I hover mouse pointer there, it goes behind the arrow).

I tried to take it's screenshot but it was not there. I took a picture using my phone.

Anyone has any idea?
It looks like one of the arrow cursors for when you hover over certain parts of the screen (resizing?). Sometimes the cursor gets stuck on certain parts of the screen. Even though I can still move my mouse, a copy of the cursor gets stuck somewhere.
