Not critical, bugs in single applications have severity 'normal', see: https://wiki.winehq.org/Bugs#How_to_report.
Does this problem also happen with vanilla (non-staging) wine?
Is there a free and legal download to reproduce this with?
Yes, this problem happens at any wine version.
To download the installer, have a direct URL: https://live-dl.mir4global.com/global-launcher/Mir4Launcher_Install.exe
You can also download from here too: https://www.mir4global.com/
The app is free to anyone download.
