Bad scrolling with pager in git bash

[Will-W]

Versions

ConEmu build: 171205 x64
OS version: Windows 8 x64
Shell: git-bash that came with git version 2.14.2.windows.3

Problem description

When I use a git command that invokes the pager (e.g. git log), I get bad behaviour with scrolling. When I'm navigating down the pager output it's fine, but when I press 'Up' or 'PageUp' the console scrollbar goes back to the top which means when I quit I have a load of nonsense from my log output all over subsequent lines of terminal.

If I use less directly to display something, there are no issues. The console scroll bar disappears completely while less is active and everything is fine when I quit less.

Steps to reproduce

[The issue is more clearly visible if you disable autohide on the scrollbar]

1. Run 'git log' on a repo with more than a screen of log output
2. Press the down arrow or page down until you are a few screens of info down
3. Press the up arrow once
4. Press q to leave

Actual results

Scrollbar jumps to top on step(3)
On quitting, the prompt is on screen at the top of the scroll range of the console rather than the bottom, and there is junk log output on the screen. Hitting enter on the console puts it a line down, but in the midst of the junk.

This is the result:

Expected results

Same behaviour as using less: no scrollbar while the pager is active, no effect on console scroll when navigating up and down. On quitting, prompt is still at the bottom of the console scrollback, and none of the pager output is visible.

I do not see "Terminal modes" column in the status bar.
How do you run git bash?

[Will-W]

The command is:
set "PATH=%ConEmuDir%\..\Git\usr\bin;%PATH%" & "%ConEmuDir%\..\Git\git-cmd.exe" --no-cd --command=%ConEmuBaseDirShort%\conemu-msys2-64.exe /usr/bin/bash.exe -l -i -new_console:p

I assume that must have been set up automatically?

[Maximus5]

If you run git-bash.exe standalone (mintty, no ConEmu) you'll see same behavior - scrollbar is not disabled.

[Will-W]

True, there is a difference in behaviour in mintty between less and the git pager. Mintty doesn't jump to the top when you press 'up' in the git log output though. It's that jump in ConEmu that's the actual problem.

I can confirm that this issue appears to be fixed in 'Build 180114 (alpha)'.

Thank you!
