I cannot see the cursor in DrRacket. (not the mouse pointer) It is too thin and close to not visible at all. I can't find a way to adjust it. Is there a way?
Seems strange, cursor is thin but i have not this problem,i suppose it depends of system font and monitor resolution.
Try in preferences (DrRacket -> settings) to change Font or Colors.
Or use Emacs,Vim or another editor as i do it.
There is too little information to go on.
macOS, Windows, Linux?
Resolution?
Screenshot?
If Linux, try an integer backing scale:
