Thanks! Actually, I don't believe that what I've seen is related to the issues in the linked item. I have, however, since figured out a work-around that seems to improve useability of RStudio on my laptop.
The annoyance mentioned is on a Del Latitude 5480 laptop running Windows 10. The current and preferred resolution is 1920 x 1080. Also, per the suggestions of the Windows settings dialogue, I leave "Change the size of text, apps, and other items" at 150%.
If I open RSTudio as is with these settings, the text is so large as to make the Windows unusable (screens are about 20 characters wide), and, as mentioned, the cursor in the console is invisible below the bottom of the screen. I have since found that I can solve the latter problems by setting the task bar to appear as needed (Lock taskbar off, automatically hide in desktop mode on). In the "Zoom out/Zoom in" options in View, I then adjust so that 78 characters (e.g., "#===...") just appear in the top of the script window. For me, RStudio usability on this laptop is then optimized.
