Every few games I play, some of the text gets messed up. The buttons in the main menu lose their labels, and annotations on the map have an unreadable block font, although the chat does still work.
Also, the numeric height indicator on the raise/lower terrain terraform sometimes isn't there, which matters if I want to make a wall exactly high enough to stop enemy units. Restarting the application is the only way to fix these issues.
I noticed these issues when I installed zerok from the .tar.gz installation script. The vanishing terraform numbers motivated me to try the semi-portable archive install instead, but that didn't solve any issues. I'm on ubuntu 18.04.4.
