strange scrolling behavior when toggling on-screen-keyboard visibility
Created by: helguson
- Device: FP2, bluetooth keyboard
- UT channel: 16.04 rc
- UT build: 2018-W29
- terminal-app version: 0.9.0
Steps to reproduce
- start terminal-app and enter passcode
- execute some commands that create a lot of output e.g.,
nano -h
to fill the screen - make on-screen-keyboard disappear by swiping it down or switching to another app
- make on-screen-keyboard appear again by taping the keyboard button
- start writing a new command
- press
backspace
Expected behavior
- on 3. command line sticks to lower border of available screen
- on 4. command line sticks to lower border of available screen
- on 5. the written symbols appear in the visible command line
- on 6. the last symbol disappears in the visible command line
Actual behavior
- the beginning is normal
- on 3. command line stays in its position creating empty screen space underneath
- on 4. command line jumps a few lines down ending up invisible behind the on-screen-keyboard
- on 5. the screen stays in this position; the command is written without being visible
- on 6. the command line jumps back over the lower border of the screen
Problem
- scrolling without the user's intention and command line hiding is unpredictable behavior that hinders working with the terminal-app
Additional observations
- taking a screenshot after 4. makes the command line appear already on 5.
- after 3. the current position marker is empty
