Indeed it fixes the issue for me and I don't find that not being able to detach/attach windows by dragging them is really a concern when we have a button to do it. I think this report can be closed.

As mentioned in comment #2, this issue was fixed in bug #38785 for windows. I have pushed changeset
which now implements the same way for handling floating widgets on all platform as it has been already used on windows platforms.

While this might also fix the known issues of floating widgets in KDE, this approach has the drawback, that dragging a dock widget only works for changing the dock location within the main window. It can not be dragged outside the main window to make it floating and vice versa. Instead the (un)dock button in the title bar has to be used.

A possible solution to this issue is handling floating widgets by ourselves as it is done in windows, where the problem already popped up with Qt4 (bug #38785).

While playing around with this solution I stumbled over a possible solution for the related "two-step-redocking" of floating widgets under windows as described in bug #38785. I have pushed changeset
which improves this re-docking behavior. I have tested it in Win 7 and 8.1, but since I am not using this platform on a regular basis, feedback from window users is highly welcome.

I can confirm this behavior on linux mint 17.3 (based on ubuntu 14.04). I also marked this bug as a regression since we need to switch to Qt5 (the default for most modern distributions).

With Qt5 - at least on Ubuntu Unity - floating dock widgets do not behave like independent windows anymore:

  • floating widgets are always on top of the main window
  • when a floating widget gets focus, the main window is also raised up, preventing, e.g., having the floating editor aside another application
