Moving an Eclipse Window to Sierra

Question

I just upgraded my MacBook to macOS Sierra. I have this weird problem with Eclipse, where every time I try to open something using autocomplete (Cmd + Mouse Hover) or even if I just hover over the element that connected Javadoc, the console window I keep on my a second monitor, snapped to my main monitor and covers everything that I find.

Before hovering:

After guidance:

For reference, I was hanging over list.add on line 23.

Does anyone know why updating Sierra causes this behavior? I can attach a console window inside Eclipse, but it’s not, but it hurts because it reduces the code editing window. Usually I have a package explorer and Ant tabs open, so docking the console makes my code window positively negligible.

Any corrections or even reproductions would be depressing, so I know that I will not be completely insane.

Update: this is not just a console, any window that is not tied to the main Eclipse window will demonstrate this behavior.

Answer 1

Uncheck the last checkbox (Displays have separate spaces), it has other drawbacks, but it fixes 2 eclipses of the window on multiple monitors.

EDIT: Still working on High Sierra
