Most (but not all) duvets and duvet covers have ties/loops to tie the corners (and sometimes the midpoints) off to keep this from happening.
Honestly I never had this issue nor knew about the loops/ties until I graduated from a full/queen cover to a king size one and it became a real problem.
For the first three decades of my life my duvet had the loops but the cover didn’t have the ties. I just thought the loops were something to grab on to while spelunking into the cover to insert the duvet 😂
I’ve never understood those. Clearly yes, they’re for tying the corners, but how? Wouldn’t they just slip out? Do you have to just tie really really tightly?
Anyway, my duvet is a King on a Queen bed, and I still don’t have the issue, but I don’t toss and turn too much.
On a king I still find that it sags a lot in the middle of the edges even with the corners tied. So we got the magnetic fasteners (like on anti theft clothing tags) to pin the middle.
As another post said the corners have a loop for the tie. Even without those loops I’ve tied the cover around a section of the duvet corner without issue. My cover is linen, so maybe other materials don’t work as well? YMMV.

I have been around for 3 and a half decades and I’ve never had a duvet that’s done this in the UK

Same, and I even buy my duvets from IKEA …
The ones I have from IKEA, no.

Duvet inserts usually have a loop on each of the corners for the ties on the cover to tie on.

That’s a clever solution!
They’re actually sold for that purpose so we weren’t that clever :)

I thought I was so clever when i discovered this myself one day. Then i used it and it torn the string off the duvet cover :/
In my experience, only the fancier brands do this. But you can make your own and sew them on too.
