iPhone Blurry in top left corner

Just suddenly happened to my iPhone 11 ios 14.2 Even screenshots have the blur. The power off screen does not. I rebooted it while plugged in, for whatever that is worth, and the problem went away. This is some sort of rendering bug, and the power off screen must use a different rendering system.

For me the problem is 100% reproducible. I have an iPhone XS running iOS14.4. Each time an application makes use of the horizontal mode, e.g. make a photo with the Photos app and try afterwards to look at it horizontal mode, or I look at a photo in WhatsApp, it occurs.

Settings - Display & Brightness - Appearance: Dark -> Light or Light --> Dark, immediately overcomes the problem until the iPhone is used the next time in horizontal mode.

Had the same problem. The suggestion of switching the display from light to dark and back again worked for me.

I turned off the Zoom display feature and it stopped.

Happened to me this morning, it’s an easy fix. Go to settings, Display & Brightness then switch from light to dark. Should 100% get rid of that weird blur. If not reset and it’ll be back to normal.

This happened to me a a few mins ago and decided to research about what caused it. luckily i’m not the only one that experienced the top left blurry thingy, if ur experiencing the same thing and don’t wanna restart ur phone just go to the display setting and keep on switching the “Light mode” & “Dark mode” and it should go probably away on its own.

I started having the same issue for the past couple of hours! I just restarted my device and it is now gone, I haven’t tried the settings thin.. just a restart and it’s gone for know. I hope it doesn’t keep happening!

TriggerAnge, go to settings, display & brightness. Then change to dark background and back to light background and it should fix the problem. It worked for me!

Happened today and just changing display and brightness setting worked (for d=from dark to light)

It did it with me too, i did the light and dark mode which ckeared it but it would cone back the. I just restarted my phone and it fixed the issue

I just tried the changing the screen mode from bright to dark. That didn’t work, so I powered it then back on & it fixed the problem 🤠

This just happened to me ! Go to settings, display and brightness, and switch from light to dark and back. It will get rid of it 😊

This happened this morning after newest OS update 14.4.1. I changed to dark display, it disappeared but I don’t like that mode. Switched it back to light mode display & it stay gone. Just like jarmarl comment below.

Restarting actually fixed it as display settings solution is only temporary. I don’t know how long it’d last but hoping that Apple fix it soon.

I restarted and it went away
