Ever since I updated to IntelliJ 6.0 I have been experiencing problems with the IDE rendering correctly on the screen. Sometimes I will have a file open that I am editing and all of a sudden the contents of the file will go blank, then when I click inside the file, some of the contents are re-rendered... if I am careful and click all over inside the file, the contents come back - but the second that I try to scroll up or down the whole file goes blank again. The scrollbars also disappear and re-appear. It is making it extremely difficult to get anything done. Has anyone else experienced this problem?
