I have a problem with Flash not responding on some websites. One such website is http://www.webupd8.org. The page will freeze for a second or two, and then a message that says "Flash has stopped responding" will appear at the top of the page. I have to click "Stop Plugin" before it starts working again. I only need Flash for some sites (Twitch, Google Play Music), so I have it disabled in chrome://plugins, but it's annoying to re-enable every time I need it.
How do I fix this issue? It's the first time I've had it, and I don't know where to start. Only system stuff that I've changed on this computer is I've enabled the CFQ I/O scheduler instead of deadline for improved responsiveness (add elevator=cfq to GRUB options), and installed TLP for more battery life. There is no /etc/adobe/mms.cfg file, but from what I've gathered Chrome's version of Flash doesn't use that config file anyways.
I have all the latest updates installed.
EDIT: I've tested the beta version of Google Chrome, and the issue doesn't happen there. If I can't find a fix, I'll use that until it's fixed in the stable branch.
