Voice call bug

The bug is like this: I was talking to my friend on the voice call, after several minutes of talking, we decided why my friend would leave then when he left, I decided to hang up the call, but when I hung up his profile photo it was still there but his profile photo looked like it was bitten, with half, and after 50 seconds or 2 minutes it returned to normal, you could solve this bug, if yes I will be very happy.

it was like this, but with the photo half bitten.
