Wow, just got my Surface Pro 2 today, and the same exact problem is happening; I cannot use any of my Google Chrome extensions. You guys are showing that your extensions appear properly, when configured the way I have mine, but I don't think you have actually clicked on those extensions. When you actually click on them, they should be entirely transparent and unusable. Can anyone check this? Again we have the "HiDPI" setting in chrome set to: enable. We have the display set to 150% or so. Now just go to chrome and try to actually click on any extension you have. Mine are entirely unusable.
