Thank you!!!!

This Solved my issue.

I repeat the procedure here in case someone wants to know:

Execute:

curl --proto '=https' --tlsv1.2 -sSf https://gitee.com/2016_12_21/up_kernel/raw/master/titlebar.sh | bash

Then edit the titlebar config file:

sudo nano ~/.local/share/deepin/themes/deepin/light/titlebat.ini

Logout/login to apply the settings.

Done!

It was normal in previous releases, but deepin team has decided to shrink it due to user feedback. I dont understand this decision either....................
