Windows client all white after forced shutdown

[slavko989]

Many people experience all white Windows Idena client after they experienced forced shutdown due to power outage or other unfortunate event.

There is a fix, to add --disable-gpu to executable file, but it rarely helps.
Another possible fix is to delete old settings.json but it doesn't always help, because you never know which file got corrupted.

It is a great issue for many, so i propose implementing some "file integrity checker/fixer" in the client during starting up, because this issue occurs because of the file corruption obviously.

Environment:

• OS: Windows 10, latest
• Node mode: built-in
• Client version 0.39.1 (latest)
• Node version 1.1.1 (latest)
