Integrated Terminal display glitches

Having a weird issue with the integrated terminal. It doesn't always happen, and usually takes a few hours before it does, but it's like the entire IDE temporarily goes black, but reappears after a few seconds and everything is back to normal - expect the terminal, which now displays either entirely blank, or like this: https://imgur.com/a/WFp6G3X

Where most (if not all) the characters are missing. And the problem doesn't go away. If I type in the terminal, or am running a task (in this case, an NPM task that auto-refreshes on save), everything still works normally. I just don't see the output of the text. Which is a real pain when trying to read error messages.

The only fix I've found is to kill the task, and close all terminal sessions, then start a new terminal and relaunch the task. Not the end of the world, but when this happens 3 or 4 times a day, it's a real headache.

I've seen other posts where the terminal is broken from the beginning, but nothing that describes the behavior I am seeing. Has anybody else stumbled onto this problem?
