Cannot See Logout Button

When I clicked on my icon image, there is a drop-down menu. But I can only see until "Keyboard shortcuts". The "Logout" is hidden below the taskbar.

What should I do?

 

Put this link into your browser then click Enter. It will ask you if you want to log out:

twitter.com/logout

 

Thank you. It works. But is there a way to fix this "hidden" logout problem?

 

On which device is it hidden? It shows just fine on my laptop.

 

My Dell laptop.

 

I'd suggest downloading a different browser like Chrome or FireFox.
