When I first used Chrome on a new tablet in fall 2013 (Windows 8 was on the market for a mere 12 months by then), I noticed that the touch events were all placed wrong. I touch the screen and Chrome will handle a touch event at some coordinates that are certainly nowhere near where the screen was touched. That's in desktop mode, not Metro. Ok, locate the Chrome executable and change compatibility mode to "Disable scaling on high DPI settings". Then try to navigate the chrome setting page to do some default scaling, which means everything now works right, except the tabs on the top are really small.
Fast forward a few months, install a plugin, only to have Chrome tell me that it won't install the plugin because Chrome does not support NPAPI. It turns out NPAPI is really not supported in Metro mode. Which I never used! I use the desktop mode, where according to Google, NPAPI is supported. Some developer confused Metro mode with Windows 8, and it seems Google doesn't have the cash to affort a testing department with even a single Windows 8 tester. So NPAPI is deactivated for Windows 8, even the users who couldn't care less about Metro Chrome, a.k.a. me. Back to the compatibility settings, set Chrome to run in Windows 7 compatibility mode.
I do understand that mistakes happen, and that's what the compatibility settings are for. But not having fixed this stuff 12+ months after it's first been reported? WTF!
