Window arrangement preview only shows windows for one monitor
iTerm2 3.3.9, MacOS 10.15.3
I have two monitors, so in the preferences->Arrangements window, the preview pane correctly shows two blue boxes arranged in the layout of my screens. However, it only shows the iTerm windows that are configured on the main display. The second display is just a blank box.
My custom arrangement has two windows on the main display, and two others on the secondary display. When I open this arrangement, (I have it as the default on startup) all four windows appear, all in their correct positions across both monitors. So it appears that the window arrangement is working perfectly, it's just that the preview representation of this arrangement is not drawing all of the windows on it.
Detailed steps to reproduce the problem:
- Open some windows across both displays.
- Choose Window->Save Arrangement from the app menu, and give it a name.
- Open the preferences, go to the arrangements tab, then click on this name.
What happens: The preview pane will only show windows from one of the displays.
What should have happened: The preview pane should show the window layout for all of the displays.
