I know it's caused by themes as some themes has it and some don't. But I really like to keep my mint-Y-Dark theme as it looks awesome. And thus, this question arisen, I know there are some codes to it and editing them will resolve the problem but I don't know what code it is and from where is it in the mint-Y-Dark theme folder. I am using Linux mint 18 Cinnamon.
Mint-Y theme folders:
~/.themes/Mint-Y ~/.themes/Mint-Y-Dark ~/.themes/Mint-Y-Darker
It should be in ~/.themes/Mint-Y-Dark/cinnamon/cinnamon.css

Instructions from GitHub on editing:
Do not makes modifications to the theme directly in the usr/share/themes directory. These are automatically generated from the files located in the src/ directory. Each subdirectory contains its own individual instructions on how to edit. Once edits are made you can generate the final themes by running the build-themes.py script.
Best would be a regular update the icons and themes using a script:
#!/bin/bash mkdir -p ~/Downloads/themes-mint/ wget -O ~/Downloads/themes-mint/themes.zip https://github.com/linuxmint/mint-y-theme/archive/master.zip wget -O ~/Downloads/themes-mint/icons.zip https://github.com/linuxmint/mint-y-icons/archive/master.zip unzip -o ~/Downloads/themes-mint/themes.zip -d ~/Downloads/themes-mint/ unzip -o ~/Downloads/themes-mint/icons.zip -d ~/Downloads/themes-mint/ cp -r ~/Downloads/themes-mint/mint-y-theme-master/usr/share/themes/* ~/.themes/ cp -r ~/Downloads/themes-mint/mint-y-icons-master/usr/share/icons/* ~/.icons/
Save it as a text file in your home directory, name it e.g.
update-themes and run
chmod 700 update-themes, then always use it like
