The Gambas 3 IDE uses the gb.qt4 component. Check which version of Qt is 
installed on your system.

Recently Ubuntu upgraded to Qt 4.8, and apparently it changed the way 
text was drawn on the screen.

Check which widget theme you are using (i.e. note it, and change it to 
see if it changes anything).

If you use Ubuntu + Unity or Gnome, Qt applications like the Gambas 3 
IDE uses the "GTK+" Qt theme that uses the current GTK theme to draw the 
Qt widgets.

Try to use KDE or XFCE or LXDE to see if it changes anything.

Check the screen resolution in DPI as configured by the X server 
(xdpyinfo command).

Check which antialiasing mode is used (which hinting, which sub-pixel 
antialiasing mode).
