[windows] [wsl] [:wx] Screen tearing when rendering :wx frame inside WSL.

[c4lliope]

Describe the bug

A colleague enabled WSL on their Windows machines and ran one of my apps that uses a wxWebView.
The app came up horribly pixelated because the frame seemed to apply dimensions improperly to the frame;
some of the frame rendered outside the bounds of the window in the horizontal dimension,
and caused the vertical columns to skew badly and make the page unreadable.

This seems to happen also on the :wx.demo() inside of WSL, and had been checked both on NVIDIA and AMD graphics cards.

To Reproduce

On Windows, run in powershell: wsl --install
Inside a WSL shell (easy to access using VS Code): iex -e ':wx.demo' (or similar using Erlang)

Expected behavior
Proper rendering

Affected versions
Erlang 26, possibly others.
Precise shell.nix being used is inside codebase:

Since erlang is only a wrapper on wxWidgets, I can't see how we can do anything about that.
Maybe ask questions in the wxWidgets mailing list or forum?
