Diagonal green line on s24

[westcostea]

I've detected this issue a few days ago on my Galaxy s24 , there seems to be a green diagonal line in the top corner of my messaging app ( telegram ) which appears randomly, sometimes it's longer or shorter

You can see it in the video,  ( top right corner) , so far this issue was spotted only while using telegram.

Any help would be appreciated

Probably something to do with updating
If its only the telegram app. Be worth contacting the app developers to bring it to their attention
Not noticed it on my app

The fact it shows up in a screen recording means it's not a screen fault at least. Try changing your chat background, loots like a minor rendering glitch.
