Some buttons have become rounded in the Customizer (Chrome).

After Chrome update to version 62.0.3202.94 (Official Build) (64-bit), some buttons (Device buttons and Back button) have become rounded in the Customizer.

Defining a border radius in these buttons fixes the problem:

.customize-panel-back, 
.customize-section-back,
.wp-full-overlay-footer .devices button {
  border-radius: 0;
}

Created patch for remove border-radius.

I have checked and noticed same thing in chrome. So I have created patch 42648.diff

Yeah it‘s a chrome feature in the newest version. All buttons are getting a border radius by default on macOS.

Worth noting seems the Chrome team decided to revert this "feature" in the next version. See ​https://bugs.chromium.org/p/chromium/issues/detail?id=752450#c13

Sounds good!

Seeing as this change affects only Chrome Canary and will be reverted long before WordPress 5.0 is released, I think it's safe to close this as a wontfix.

Apologies, Chrome 62 is stable.

We could fix this in 4.9.1, or not worry about it.

Let's see if this is reverted in Chrome by the time we have a 4.9.1 release date in mind. I wonder if it's worth adding in an explicit lack of border radius just in case something like this happens again :/

It looks like Chrome 63 will be released early December, so probably a month before 4.9.1. Given they explicitly are undoing the border radius, I highly doubt they'd re-introduce it.
