@bsclifton Can you reproduce and check if a flag changed?

Reproduced; looks great at 100% but then gets blurry at 125%. I made sure to log out and log back in after upping my DPI to 125% too.

Here's a screenshot that (hopefully) shows how blurred things get (be sure to click to see image at it's full size):

I tried the command-line options shown as a work-around here without luck (and many variations of it):
https://bugs.chromium.org/p/chromium/issues/detail?id=395425

app/index.js

app.commandLine.appendSwitch('enable-use-zoom-for-dsf', 'false')
app.commandLine.appendSwitch('high-dpi-support', 'true')
app.commandLine.appendSwitch('force-device-scale-factor', 'true')

window.devicePixelRatio isn't correct on my VM. In 53, it is 2 but 1 in 54.

Right click desktop > Display settings
Pick a DPI higher than 100% (ex: 150%) and close window
Logout or restart and then log back in again
Launch Brave

Except Bookmark modal(#6777) and autofill modal the rest looks good.
