Text input gets garbled - RANDOM

My specs: PC, i79900K, GTX 1070 Ti, 64GB Ram, Nvme 2GB, Game Pass Windows version.

I keep getting garbled text randomly from text input boxes in many areas of the Dungeon Maker program. I has happened in the Campaign Creator screen and during Location editing. It is totally random as far as I can tell. I input text into the text input box, and it is displayed in the game as garbled. See pics (the word Amethyst is garbled in the Custom Items list). Going back to the input box, the text looks correct. It gets garbled on re-display.

Is this a known bug?
