  To make the fix conditional I think we'd better wait until it's actually fixed upstream, so that we have the actual Qt version with the fix. And hindenburg hasn't accepted the patch yet anyway :)
  
  But if the code path that uses pixelDelta in ScrollState in konsole is supposed to handle high resolution touchpads/trackpads/... etc then checking that the event source is not a mouse can just stay in, even after the bug is fixed upstream in Qt. (I am not sure, but is that code supposed to handle high resolution scroll events coming from say an Apple Magic mouse?).

  I'll look into that, but no promises though.
