Chrome Version       : 53.0.2785.143
OS Version: 10.0
Secure Shell Version : 0.8.34.4

Also tested on Chrome OS v53.0.2785.103 stable

Secure Shell Font(s) Tested (in reference to https://bugs.chromium.org/p/chromium/issues/detail?id=648845 ): 
    - "Everson Mono", FreeMono, "Menlo", "Terminal", monospace
    - "DejaVu Sans Mono", "Everson Mono", FreeMono, "Menlo", "Terminal", monospace

These issues all started happening once updated to v0.8.34.4 on both windows, and chrome os. I have tried ssh'ing into other machines and these problems persist.

### Not scrolling & Offscreen cursor

What steps will reproduce the problem?
1.Performing commands that result in many lines of output that require the window to scroll (e.g. tree, or a large make command)


What is the expected result?
- As new lines are created in the terminal, it should scroll with them so that the current line is always visible.

What happens instead of that?
- Occasionally (about half the time) the cursor will be stuck on a line just below the window. Running `clear` will bring the current line to  the 2nd line (with the 1st line being leftover output of the last command).
- The window "freezes" on a line, requiring the user to issue a new line to manually scroll the hidden text up (enter or ctrl-c)
- The current line can offset by 1. That is, if it should be at line index 0, it is at 1. If it should be at the last visible poisition, it is just one below that.

Please provide any additional information below. Attach a screenshot if
possible.

See `stopped-scrolling.gif`. When the output does scroll, it is a result of me pressing [ENTER]
Also see `offscreen-line.gif`.

### vim background

What steps will reproduce the problem?
1.Giving vim a custom background color

What is the expected result?
- The background be that one solid color that was set

What happens instead of that?
- Each line of text receives that background color, but SecureShell's background color (black) is visible between each line of text.

Please provide any additional information below. Attach a screenshot if
possible.

See `vim.PNG` `and vim-2.png`
This, like the previous problem started occurring after the last update.
