Notes:

It happens both when using Apple BT keyboard AND when using built-in keyboard on my Macbook.

It happens when writing text AND when using shortcuts (e.g. shift+cmd+tab to reopen recently closed tabs in Chrome - often two or more tabs are reopened).

It happens in all applications.

Update:

The problem was not present in safe mode.

Rebooted again, and the problem was back in normal mode.

However, suddenly a few minutes later - the problem seems to have disappeared.


I'm glad, but confused ;)

Will post again if it returns.

I am also having this issue. I took it to the apple store, and explained the issue. I got the keyboard replaced, which I was entitled to anyway (2017 Macbook Pro). They suggested returning the machine to the previous OS to see what happened. The issue was fixed. I left it a few days, and then decided to take the plunge and install Catalatalina again (look it just happened again!). The problem has returned. I can confirm it is the shift key being used to capitalise words that causes the issue.


Look, I will now demonstrate.
