    Description

      After upgrading to Qt 5.11.1, we noticed a strange behaviour when grabbing screen contents. Grabbing a screen with no explicit geometry or the full screen geometry works fine. But when specifying custom geometry, the image gets squashed vertically. I have attached an example program to reproduce the problem with, and two screenshots for comparison.
