Thick white border around gnome terminal

Hello,

I've recently installed kali linux on dual boot.

Then i upgraded kali linux by using command
"apt-get upgrade"

After restarting my pc and logging back my pc started hanging every few minutes (which happened only after upgrading it) and when i open the terminal it had a thick white border around it

Here's the image:

I want to remove this. This might help my pc from hanging after every login.

I too searched everywhere on google but found no result.

Any answers would be helpful

Regards
