Changing the PDF page size is going to change how things are scaled to fit the page, which can throw off the positioning and size of things. So take care when doing things like that. As far as the size of the buttons, it looks to me like you may have the display scaling set to a fairly large value in Windows. Please go to the display settings in windows, and let me know what selection you have made under the "Scale" setting. If it's set to something like 200%, you may want to drop it to 150%, which will increase the resolution, which should reduce the size of the buttons.
