I am on latest Arch with latest Gnome 3. I had this working fine, but played with the native screen resolution and somehow after this exercise, my mouse cursor size is now super small in google-chrome. I tried resetting the theme multiple times including "use system theme and titlebars" with no luck. To debug, I installed google-chrome-dev, and it is working as expected. I am using the Adwaita dark theme in both Arch and Chrome.

I think I could solve this by reinstalling google-chrome but would like to debug this to figure out why google-chrome isn't honoring the gtk3 system value here.
