In macOS Tahoe the bezel is clipped on left/right sides and this makes push button look square. In previous versions of the macOS button bezel was rendered by the AppKit smaller than the rectangle we want to draw it with, and we worked this problem around by adjusting the rectangle, shifting it to the left and adding to its width (and the resulting bezel thus was fitting within the clip rectangle). In macOS Tahoe these adjustments not needed anymore - the button's bezel is rendered exactly within the rectangle we ask to draw with (and this also means within the clipping rectangle).
