I'd suggest to try the latest version from here:
https://sourceforge.net/projects/librecad/files/Windows/NightlyBuilds/master/

But because I can't say which version @GaryS used on Windows, it may already be negative proved by him.
In fact the latest version is build with Qt 5.12, when older 2.2.0-rc versions were still built with Qt 5.4, so it could be worth a try. It is in release candidate state and as stable as 2.1.3.
