I can confirm that this fixed the visual issue, but, unfortunately, it
did not fix the mouse event issue on macOS 10.13. Mouse clicks still
pass right through the frame. In order to get mouse events to work, I
have to:

1. Turn undecorated off
2. Resize
3. Turn undecorated on

Any resize after undecorated is turned on leaves the clickable area “constant”.

I don’t know if it’s any help, but https://github.com/gnachman/iTerm2
(GPL) implements a no-title-bar mode that seems to work perfectly.
It’s resizable, respects mouse events, starts w/o a title bar/borders,
etc.

For my usage I’d prefer they were resizable. Thanks!

I’m not sure. I cleaned up a few build folders and rebooted and it
built again. I was building with homebrew on that machine, so I’m not
sure if it was doing something strange. I hadn’t ever seen that until
today.

Thanks,
