Weird behavior: Writing a header the same text is added to a paragraph above

Not sure if anyone else has encountered something like this, for me this happens only sometimes and only on a specific computer (that does have some restrictions and settings that are beyond my control). Basically, I would like to know if someone knows what causes this behavior. It’s hard to debug, because it’s not systematic (or I can’t think of a reason for when it appears). I’m not even 100% sure it’s caused by any of my obsidian settings, since it only happens on one computer (could be some Windows things).

What I’m trying to do

When I’m writing a header on my post, the same text appears on the paragraph before in the body text (see image). The picture doesn’t show this correctly, but I actually see the cursor on both lines simultaneously.

Things I have tried

Not really attempted a lot, because usually when I click on the note and start again, the behavior disappears.

This doesn’t happen often enough that I’m even worried about a solution: I just would like to know why it might happen if someone has an idea. I have checked the console, and I don’t see anything happening (no lines are produced during this), so not sure what’s going on.

Maybe you’re accidentally triggering Multiple cursors - Obsidian Help? Either by moving too quickly so that pressing Shift and clicking register at the same time, or perhaps the device it happens on has some lag, a glitch, or a hardware issue like a sticky key that causes the 2 events to register together.

Altho you probably press Return twice to go to the heading line instead of clicking the mouse, so I don’t know.
