Hi @Dariusz.

So what OS and toolchain are you using?
I tried your code on macOS 10.13.1 High Sierra clang and xCode Version 9.1 (9B55). I did not see the issue you describe in the video.

I added details at the bottom of the topic, sorry for not getting it initially.

OK, I have a similar windows setup as you so I will try it on that later and let you know how it goes.

I built that on my Windows 10x64 Qt 5.9.2 Visual Studio 2015 pro.
I did not see the issue you describe in the video.

Using the same code? - just 2x checking. This is nuts then ! I have no idea how to even approach something like that o.o. Will try to run the code on my laptop see if he produces the same issue.

Yes I copied and pasted the code you posted and tested it on macOS and windows.
I did not see what you show in the video.

This makes no sense at all. I dug out my laptop/tabled that is mostly facebook used. Spend 1h setting up visual studio qt and clion. Coded up the test from the ground up, drag/drop and I'm getting the same incorrect behavior I described above. What the hell is going on o.o ?! I now have 2 separate pcs that have that issue ;/

Thanks for testing it !

Are you dragging the 1st item from 1st group and 1st item from a group in 1st group? I mean like on the gif? I noticed if I drag it differently then it works but if I do that exact move then it breaks. I don't know how only I have the issues with 2 different pcs...

Yes I tried following video.
Could have missed something but did try multiple times.

Black magic. In any case I reported it as bug and they - I think - have reproduced it as its now marked as P2. https://bugreports.qt.io/browse/QTBUG-64445
