The toolbar buttons seem to be broken in Edge when using vertical tabs with the title bar off (the best way to use vertical tabs). It really spoils the experience of using an otherwise very good browser and has been there for more than 3 months (since Edge 120 was released). When you open Edge, the toolbar is greyed out. Move your mouse over each toolbar icon, then icons look normal. However, as soon as Edge is not in focus, like if you click on another window or the taskbar, and you move your mouse over any toolbar button, the button gets greyed out again. To fix it again, you need to bring Edge back into focus and once again move your mouse over the toolbar button or buttons that got greyed out. It's very tiresome and makes the browser look cheap and ugly. I've been complaining and sending feedback repeatedly, but the Edge team is refusing to do its job properly and fix a massive bug that is affecting a fundamental aspect of Edge.
