Photoshop hourglass problem?

Pro tip!

Do you have a Photoshop hourglass problem when painting?

My machine is cutting edge too.  Needless to say I was thoroughly perturbed at the hourglass appearing after each stroke of the paint brush.  How is it even possible my machine needed to take a sec to process the most minor of processes.

Well, do yourself a big favor and turn off the histogram window.  Apparently, the need to re-asses the image for the histogram is enough for that split second of annoyance.

..whew, back to pain free painting.
