Description of the issue:
In Gnome 3, the window corner of Brave is broken. It shows little black squares as opposed to a nicely rounded corner (top left and right corners).
Steps to Reproduce (add as many as necessary): 1. 2. 3.
Install Brave with Gnome 3.
Actual Result (gifs and screenshots are welcome!):

Expected result:
Rounded corners.
Reproduces how often:
Every time I use Brave on Gnome 3 (really, any distribution, Pop!_OS, Manjaro, …).
Operating System and Brave Version(See the About Brave page in the main menu):
Manjaro Linux (Gnome version)
Pop!_OS
(basically any distribution with Gnome 3, I didn’t try all, but the above two are tried)
Additional Information:
I am running it in a VMware Player 15, it might have something to do with rendering but I couldn’t find a machine to test for sure.
