Before I fill out a bug, I wanted to see if anyone else was experiencing this.
I am running the latest EAP of RubyMine (112.219) on Ubuntu 11.10 with Gnome 3.2.1 DE. The issue is that when the application window is maxmized, the menus are detached from the menu bar. The windows is scaled by default when the program starts up.
Here is at default:
Here is when I maximize:
On top of that, when maximized, when I release the mouse click, the menu closes.
I don't recall the previous EAP version doing this, however, I was still using Unity at that point, so wasn't sure if it was a Gnome issue.
