For some time now (at least a couple of months) I am seeing 100% cpu use whenever I bring up Octopi on a browser. This is on 2 different PC's, and the choice of browser doesn't make any difference - I've tried Firefox, Edge, Chrome, Safari on a Mac.
Any ideas what would cause this or how to go about troubleshooting would be appreciated. If I bring up Octopi it pretty much kills the PC for anything else. I had to kill the Octopi tab just to be able to type this, otherwise it's too painful.
The printer is a MakerGear M3ID with included Raspberry Pi. Octoprint says it's running version 1.3.6.
