Bug involving the cursor turning invisible in a game

This has happened to me several times in the past, but I have had times where my cursor has disappeared from the screen completely while I am in the game. However, it seems that it is still there, as it can still interact with the game, such as clicking where to move, buying from the shop, etc. It retains full functionality, save for being actually visible, which, as one might guess, makes landing skillshots significantly more difficult. Closing the client and restarting seems to fix the issue, but, as with all manual restarts, is not always convenient. Because this cursor invisibility has happened before, all signs point towards the possibility of it happening again. Unfortunately, I do not have a screenshot of it, as I do not know how to take them, and spamming the function keys on my keyboard doesn't seem to do anything.
