Is it only me having this problem?

[Ilia kumaraku]

So recently i got an s10e a d i use night mode with it since it conserves battery and looks better to me.Now what ive noticed is that for example when im on my recent apps where it shows all my apps and if i have instagram open on it(direct messages page/window whatever its called)and if i swipe left to right quickly i see some weird blue line just outside of the border of the app with its content also moving.Same happens when for example on youtube home page theres a video with black color and i scroll fast on it up and down it extends with a blue line above and again the content moves.Now im just wondering is this just a me problem where my phone is buged or sth or is it just a software update issue maybe and everyone else has it.Currently on android 9 one ui 1.1

1st november security patch.
