Switching from Creator to other window changes scroll position in editor

Steps to reproduce:

1. Open any big source file
2. Put cursor on first line of code
3. Scroll down, so cursor goes out of view
4. Switch to another application in a small window, so that you still can see creator's editor

Expected result:

Scroll position remains unchanged, cursor is out of view

Actual result:

Scroll position changed, it scrolled up to ensure cursor is visible
