Sorry for the trouble. This is an issue I have seen before though it does seem fairly rare. Should you see these characters appearing when typing, try pressing Ctrl and Alt a few times. This will reset the keymap for the console and should resolve the problem.

We are experiencing the exact same issue. It seems account specific because we get the same issue on all types of machines, browsers and ips.

Any progress on getting an answer for resolving this?

DO support has not tried addressing this. Over the last few months they’d simply email links to support articles (like the “ctrl+alt” one) without actually addressing the underlying issue.
