Hi

I am getting a black screen flash when switching applications or changing a webpage, or editing spreadsheets. 

This has only just started yesterday. 

There are no error messages or flashing keys, & event after a prolonged screen blackout (say 10 seconds) things return to normal until it flashes again 

There was a windows update recently but everything seemed fine for a week or so after. I did a system restore and it seemed to cure it, but today it is back to flashing.

I'm running Windows 11 Home, version 21H2

My internet connection is wireless.

I've read it might be a driver issue, and I've run a diagnostic check and it returns as all OK.

Thanks for any advice.
