Yup. It's really helpful that someone who is capable of fixing issues gets some of the work finally done after these years of waiting. Personally, I'm fine with slight badly coding under the hood (Wine codebase) if nothing seriously breaks and the practical result is that I get rid of these annoying small bugs that have had negative impact on my daily workflow for years already.
For years I've been aware of the problem @Andrew Martin described above. I've got along with it by just docking the panels to the main program window and keeping the main window maximized. Sadly, this is not a proper solution and it's not very practical either.
There are even more issues related to windows/panels of Photoshop, such as buggy maximize & minimize behavior of the main Photoshop window (CC 2015 :: https://s21.postimg.org/7m2m99nuv/image.jpg) but that's another bug issue to be reported.
