There is a known bug in this area when you use fractional display scaling depending also on the physical size of the monitor. Fractional display scaling means something % other than a multiple of 100. For example, 150%. It is present in every version that includes Text: Rich, and I have improved it, but I cannot seem to fix it. It is an issue deep within some libraries that we use for the UI. So, you can either change your display scale or use something else for text.
