When WeChat is maximized, and I minimize it by clicking away from the program. It leaves a border outline of the application. It stays there even when I am using a different application. The only way to remove that border is to minimize the application by clicking on the icon from the taskbar.
I tried to do a screenshot of it but it doesn't show up in the picture. I hope someone understands what I am saying.
I am on Linux Mint 20.1.
