Window blanks out when opening eg. Windows File Explorer (mingw64)

[helmesjo]

Summary

Any time I have a helix instance running in a mingw64 terminal and open a fresh instance of Windows File Explorer it will (eventually) go blank at some point and I'll have to interact with it for a redraw to be triggered. cmd, powershell & cygwin64 all appears to work fine.

Possibly a bug in mingw64, but it would be interesting to know what helix listens for and whether it actually is a bug in mingw64 or just a case not handled by helix.

mingw64	cygwin64
powershell	cmd

Reproduction Steps

I tried this:

1. In a mingw64 terminal, run hx .
2. Open a new instance of Windows File Explorer

I expected this to happen:
helix window is unaffected.
Instead, this happened:
helix window becomes blank white.

This appears to have been an alacritty issue AFAICT. After updating to 0.12.1 the issue disappeared.
