Whenever I open a tool which opens the familiar 'Expression String Builder' interface, the text in the input box behaves very strangely - the cursor is offset, and text becomes overlaid. This makes it very difficult to edit expressions using this editor.
Any suggestions on what settings could be responsible for this situation?
This screencap shows an example of the poorly rendered text, the string entered is:
"SA22018_NAME" + '\n' + "2018_rollcount"
