I've been using Ubuntu 16.04 with dual 4k displays for about 3-4 months now, but all of a sudden today, the zoom level & UI size seems off in Chrome.
The dual-display screenshot has 3 windows (from left to right): Visual Studio Code, Chromium, and Chrome.
As you can see, Chrome and Chromium are arriving at different conclusions for what scale things ought to be.
Since Visual Studio Code is built on the Electron Platform, it's effectively an instance of Chrome, so that's why I included it here for comparison. The left pane w/ the file list is normally about 60% of the size in this screen shot.
For both Chrome and VS Code, zooming out 2-levels gets it roughly to where it's been all along.
So, Question: How do I fix this so that I don't have to zoom in/out in Chrome?
in Display settings in Ubuntu remain the same--both displays @ 3840x2160 res and a 1.5x scale factor for 'menu and title bars'.
My system is an i5 6600K w/ GTX 960 using the NVIDIA binary driver, v 361.45.18
the Menu font in all windows appears slightly larger than usual
