On Multiple screens on Mac OS X High Sierra. Floating windows will move back to the main screen even if it is not the intention. Steps to reproduce. 1.) Using Macintosh with at least 2 physical monitors 2.) With Independent Spaces configured 3.) Open Eclipse Photon/Oxygen, Java EE Developer IDE. 4.) Open any Java Maven projects 5.) Drag any window from the IDE to another screen/monitor 6.) Start typing on main editor window 7.) Notice that the window that was dragged on the other screen will go back to the location of the main window.
Any news with this? It makes it impossible to use the second screen. StackOverflow has more details, the problem seems to come from the fact a change in OS/X made the screen shown on a second device as an independent virtual desktop (space, in Apple jargon): https://superuser.com/questions/669758/stick-floating-eclipse-windows-on-second-screen-with-mac-os-10-9-mavericks https://stackoverflow.com/questions/41867150/eclipse-floating-windows-on-mac-os-sierra

The links mention old eclipse releases, can you please try a recent release? Link to Eclipse 2019-12 (4.14) downloads - https://www.eclipse.org/downloads/packages/
Hi Lakshmi, I was using the 2019-09 and I've just tried the 2019-12. Both do pretty awful things when trying to use two screens, not just the disappearance reported in this hereby bug. Because it's difficult to describe all the details, I've recored these two videos: https://www.youtube.com/watch?v=APkWEvBJUP0 https://www.youtube.com/watch?v=cyUQA5v7lx0 As you can see, almost nothing works: initially the floating window disappears when I try to drop it in the second screen, then after the struggle to bring it back, it is abruptly returned to the main screen as soon as I open a modal dialog. I don't have much experience GUI development, but my understanding is that the floating windows are forced to follow some behaviour of their parent, and a fix could be that they're left more free to stay where the user decides.
(In reply to Marco Brandizi from comment #3) Thanks for the videos. I'm able to reproduce the problems. Will investigate.
The behavior is also seen with a simple SWT snippet with parent and child Shells. The problem seems to be that the parent and child shells can't be on different spaces.
