Problem

Under certain settings, a compatibility issues can appear between Java and some graphics card drivers, which results in the text from the editor (in Author or Text mode) being displayed garbled.

Solution

If you encounter this problem, update your graphics card driver. Another possible workaround is, open the Preferences dialog box (Options > Preferences), go to Appearance > Fonts, and set the value of the Text antialiasing option to ON.
Note: If this workaround does not resolve the problem, set the Text antialiasing option to other values.
