title: Android Studio 3.3 bug
body: <p>I recently upgraded to Android Studio 3.3 and I've been working on projects using the IDE for the last week. I've noticed that a times the java files are corrupted and do not open correctly. See the image. 
  What might be the issue considering version 3.3 has been released in the stable channel. <a href="https://i.stack.imgur.com/kLbn5.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/kLbn5.png" alt="enter image description here"></a></p>
