=== Corrupt Textures on ATi Cards ===
Several users have reported corrupted textures running FlightGear on ATi graphics cards. The ATi drivers are the subject of intensive improvement, but can still be problematic for some users. Try this:
Start FG in the normal way.
Select 'View' drop-down menu (one from the left- you may not be able to read the labels!)
Select 'Rendering Options' (fourth choice)
Uncheck 'Use Point Sprites for Runway Lights' (fourth check-box)
When you come to quit FG, do so by menu: File...Exit, rather than closing the window to save this setting.
If you can't read the Menu titles (because of corrupted graphics) you can manually edit the config files [[$FG_HOME]]autosave.xml and/or [[$FG_ROOT]]/preferences.xml before even starting FlightGear. The file autosave.xml is created the first time FlightGear is closed and settings in it override the defaults in [[$FG_ROOT]]/preferences.xml. Use your operating system's search facilities to find the files if you don't know where to look for them. Close Flightgear and change the line
<point-sprites type="bool">true</point-sprites>
to
<point-sprites type="bool">false</point-sprites>
in both files (if you don't have an autosave.xml it is sufficient to make the change in preferences.xml) and start FlightGear again. This is the same as changing the above mentioned option in the rendering dialog but does not require FlightGear running.
