When running IDLE on a fresh 2.7.6 install on OS X 10.9, I'm seeing the following message generated periodically:

CoreAnimation: warning, deleted thread with uncommitted CATransaction; set CA_DEBUG_TRANSACTIONS=1 in environment to log backtraces.

Since the message is coming from Cocoa layers of OS X, this is undoubtedly a Tk issue, rather than a Python issue.  What version of Tcl/Tk are you using:  ActiveTcl  Suggest you open an issue on the Tk bug tracker and/or the ActiveState bug tracker.

Following the instruction in the log message would also be useful, that is, in a shell window:

$ env CA_DEBUG_TRANSACTIONS=1 /Applications/Python\ 2.7/

With some luck the stack trace will point to the source of the problem. As Ned wrote, that source is probably TkCocoa.
