    • qtbase 319cbb7597100f3b65792dc6a0ce2885ce6c0e8c 4.8 6c3b032693acf86a894a8ea3a30c937a1d08ed7f

      With the attached example if you compare the output to what you get in 5.0.x and 4.8.x then you will see that the two lines should appear in the same place, whereas in Qt 5.1.0 and 4.8.5 the red one is a diagonal.

      This is a regression against Qt 5.0.2 and Qt 4.8.4.
