While preparing games, I create many handouts for the needed rules, these are normally copy/pasted from the simple HTML version of my notes. After creating a number of handouts the CPU will end up stuck at 100% (one core) with Chrome/Chromium being the hog. Sometimes this occurs after creating two handouts and sometimes I only notice after half a dozen. Hitting F5 and reloading the browser window resolves the issue until a few more handouts are created or edited. Operating System: X11 Linux x86_64 Web Browser: Chrome 53.0.2785.143 (But was present since at least Chrome 47.x) No browser extensions are being used. The problem does not appear to appear on Firefox, but I have only done limited testing there. This may be related to old/closed bugs about character sheets causing lag and high CPU, but no characters sheets are involved here.
