Same thing happens to me, but only after my phone rotates from portrait to landscape and back. Doesn’t happen all the time; maybe 50-60% of rotations. Force closing the app and reopening fixes it for me.

this happens to me at times

You also happening to me on iOS 18 when screen rotation is turned on; usually happens when I rotate by accident and it rotates back immediately. Only fix is swipe close and restart app

I’m getting this too.

The app after force quitting and restarting:

This happens to me on Android, but it happens whenever I make a comment on a post. My window shrinks after I submit and stays that way until I close the app and reopen it. Here's a before and after from about a week ago:

Happens on android too. It's fixed as I write this comment but comes back as soon as that screen goes away (saying fixed while the animation plays)

Man, and here I thought this was specific to the stupid new glass UI on an older iPhone model.

Got the same happening to me on android too.
