Using Linux Ubuntu 20.04.3 in a VM using X11 mozregression-gui 4.0.18 to view Firefox 88 produces a Firefox that does not render the icons for the minimize, maximize, and close buttons regardless of the Ubuntu theme unless Title Bar is checked in the Customize menu.

Running ./mach mozregression renders the browser correctly, and does not trigger the same issue.
