Root Cause
The problem is caused by an incompatibility of the configured Java Look&Feel with the graphics card driver. It can be sovled by using another Look&Feel.
Solution
- Edit the file MIBDesigner3.cf in your home directory.
- Remove the line that starts with LookAndFeel=.
- Save the file and restart MIB Designer.
