    Description

      In a ListView element with 10,000,000 elements the spacing of the delegate paintings becomes odd at element 3355444 for some reason.

      See the attached image and example code for a demonstration. Will test whether it is the same on Windows and Mac and update this bug.

      Not sure if this is the correct project to file this in. Feel free to move it to the correct one.
