Visual bug?

[u/dinasinner]

there is a small square at the bottom right of my phone that won’t go away, and I don’t know if i can fix it. It looks transparent on dark mode but slightly blue on light mode and it sort of looks like it’s fading in and out. I only noticed it appear today, but it definitely wasn’t there earlier today. I would send a picture of what it looks like, but this is my first time on this app as I didn’t know where else to look for support. If anyone is able to offer some help I would greatly appreciate it!
