LazyGit exits unpredictably while moving quickly through commits (on WSL only)

**Describe the bug**
When I move the cursor (up/down keys) through the commits (reflog) the app crashes. This only happens on WSL, not on my Mac (that works perfectly). Strangely the problem seems to happen less if I use the '-d' debug flag.

**To Reproduce**
Steps to reproduce the behavior:
1. Open `lazygit` in any repository directory in WSL
1. Use `left/right` arrows to move focus to the `commits` pane
1. Quickly use the `up/down` keyboard keys to shift focus. While I haven't been able to confirm this, it might be a race condition because some change sets are quite large.

**Expected behavior**
It should move focus without exiting.
I say "exit" because I get no logs in the console.. so it may not be a "crash" per se.

**Desktop (please complete the following information):**
- Windows 10 WSL (Microsoft Windows [Version 10.0.18363.592])
- Lazygit Version: commit=, build date=2020-01-10, build source=debian, version=0.13, os=linux, arch=amd64
- ConEmu 191012 [64] Startup Info

**Additional context**
It may be worth noting that I use "ConEmu" too, so it could be some strangely confluence of circumstances.
