  Corrupted display of Qt4 Applications

Status in xorg package in Ubuntu:

Bug description:
  When I run Qt4 based Applications either from konsole or from Creator the windows' content will look very disturbed, rendering the program absolutely useless. This happens only if Android Studio is running at the same time (Version 1.4, JDK 1.7.0_79). If I close Ansroid Studio (almost) everything is fine again. (Well almost, as there's also a problem with Qt4 command link buttons and HiDPI displays, but that's another story.)
  The applies for file dialogs in chromium (it uses kde4 libs, I suppose?). When AS is running, the file dialogs will be unusable, if I close it all is good.
  I haven't tested it with other Java based applications yet, so it might just be the JDK. (It's the Oracle one, I think, or whatever Google makes you download.)
