The GIF below shows what I'm observing. If I do the following
- I send Vim to background with Ctrl-Z only once,
- come back to it via fgEnter,
- then open another terminal, causing the original one to resize
upon performing step 3, Vim is sent to background automatically.
This seems to happen irrespective of the shell. In the GIF below you'll see that happening with both bash and sh, but I can also reproduce it in fish.
This is clearly being a fairly annoying problem, which I started experiencing yesterday. Initially (when I asked this question on vi.stackexchange), I thought it was related to two specific plugins, but as you can see from the GIF below, I can reproduce it without using any Vim settings (launching it with the -u NONE option). However, I've not been playing around with config files, recently, so I don't understand why this problem suddenly popped up yesterday. Maybe some system update?
