I've had this issue for months now and it has been driving me mental. Ever few weeks after installing an update the font sizes in my browsers (both chrome and Opera) change sizes and they're independant of each other. I've had Chrome being normal and Opera's fonts being wacky and vice versa. Sometimes the fonts are huge and I can only see a few letters in the tabs. Other times they're miniscule, like now.
I just restarted my system and now they're BOTH tiny.
I've uninstalled and re-installed. I've googled everything. All I can find is a bunch of other people complaining about the same issue in Chrome with no solution.
I'm going nuts with this issue, does anyone know of a solution?
