If your display driver crashes while scrolling in jDeveloper and you get the message saying "Display driver stopped responding and has recovered" then this is the thread for you.
This can be fixed by modifying jdev.conf file. This file can be found at $JDEV_HOME/jdev/bin/jdev.conf or jdevbin\jdev\bin
Close jDeveloper. Make a backup of this file somewhere. Now go to the original file and add this line at the end of file:
AddVMOption -Dsun.java2d.noddraw=true
Save the file. Now start your jDeveloper (it may take 2-3 minutes for the first start after this). Scrolling should be fixed now.
If for some reason your jDeveloper does not starts then replace the original file back in jDeveloper.
