UI issues on 4K display

My display has a non-1x scale factor, and some buttons (e.g. stop debugging) are quite hard to press. The screenshot might look fairly normal on a display with a smaller DPI, so I've attached a photo of the buttons next to the tip of a pen for comparison (the pen is pressed against the window, just in case there is any doubt ).

The text is also lacking some vertical padding ("Debugger", "Application Output", etc.).
