Yikes and to be honest I am somewhat stumped why this could happen.
If you are up to this and it is optional.
1 - Restart in Safe Mode. This will perform a Disk Repair, clear cache files and only load Apple Software, extensions and fonts. The boot up will be slow and can take some time - Normal.
2 - Safe Mode will also eliminate Third Party Software, extensions and drivers from loading. It will only load the Minimum amount of Core Apple Processes to allow the the computer to function at a reduced Level of Performance
3 - Does the issue present in this mode ?
Should the issue still present, it maybe time to Open a Service Ticket with Apple Support
Get Support Choose a product and we’ll find you the best solution.Start now and open an Apple Support Ticket as they are Apple Employees to deal will these types of issues .
The above is well worth your time to Make Apple at least aware of this issue and perhaps bump it up the " Food Chain " to the Apple Software Engineers
Time permitting, I am personally interested in what may come of this encounter with Apple
