I recently got a monitor with UHD support and... I can't comfortably use it with FF on its native resolution (3840×2160): everything is just too small even with UI scaling set to 140%. If this can be worked around for chat windows (by increasing the windows and increasing font size), it seems impossible to do the same for other elements. Like inventory and actions and other menus are still smaller, than I'd prefer and can't be scaled a bit more and some elements do not scale at all (like the menu called out by "start" button on gamepad, buttons on chat windows, pop-up messages (those like "Hydra's eyes now glow blue") and some others).
Is there something I can do to improve the situation or should I just hope for some changes in future patches and use a lower resolution meanwhile?

Thank you
