Rory - good thinking. Screens now come with much higher resolutions than were probably envisaged when OOo was originally written. The requirements merely say "1024 x 768 pixel or higher resolution ..." My screen is 1,920 x 1,080 and works perfectly.
The blurred bit seems to be 64 pixels wide in the uploaded image which suggests a coding or hardware problem as it is 2^6 = 64.
Also, open a simple text editor like Notepad on Windows, or even an email editor. Copy the AOO text to it. Does the problem still occur when you use the same font as is used in AOO?
