title: Android Studio IDE does not show dialogs' content on Ubuntu 15.04
body: <p>Does anyone experienced and know how to fix this issue:</p>
  
  <p>Android Studio sometimes (randomly) does not show any content in dialogs (find, commit, compare dialogs). It takes a part of screen which was visible in that area where dialogs appears. And content of dialog is not refreshed and not visible at all.</p>
  
  <p>All functionality of that dialog works, just I can't see anything.
  Here's how it looks like:

  <p>Anyone knows how to fix this?</p>
  
  <p>I'm working on Ununtu 15.04 with Android Studio 1.2.1.1, which is based on IntelliJ IDEA.
