Last night, I updated my version of Google Chrome from 43.0.2357.81-1 to 43.0.2357.124-1. The most visible change is that the UI elements are way too large. Here's a comparison with Chrome (top), Firefox (center) and my system fonts (bottom); only Chrome is wrong:
This isn't a page zoom issue. Chrome thinks my zoom is at 100%. I can shrink the page elements by zooming out, but the UI is still too large.
I can fix this by launching Chrome with the --force-device-scale-factor
flag. However, this isn't really a great fix; I'd have to change my launcher shortcuts and any programs that launch Chrome (e.g., web servers that auto-launch a browser, like Racket's). Using this flag also causes Chrome to start with a very small window size.
I checked in chrome://flags
and didn't see anything interesting matching the grep for "scale."
If relevant, my desktop environment is Cinnamon on Linux Mint 17.1 64-bit. My screen resolution is 1920×1080, on a normal 14-inch (157 dpi) display.
