I think cinnamon should allow users to remove the shadows that surround windows. To me it is an annoyance and I can turn it off in Windows. It is just more wasted screen real estate that actually gets in my way from time to time.
I think it would be better to have more control over the color, size, etc. of the shadow
Please implement this.

I'd like to have that too. Windows tilled with gTile look terrible when they slightly overlap each other when changing focus.

Has this still not been implemented?
For anyone who, like me, found this issue long before finding a solution, here is one that worked on my system: as root, edit _/etc/environment_ and add MUFFIN_NO_SHADOWS=1 and save. Then log out, and log back in. Tada!
Here is a screenshot of a window and menu w/out shadows, along with my system for reference:

I agree, it'd be nice if this were a preference exposed in the settings, but here's a work-around for now!
Seems logical to add it to the Appearance preferences in Interface.

I have Cinnamon on Fedora29. There is no /etc/environment :(
Do you have ~/.profile (in your user's home)?
You should be able to add the environment variable there in this format.
export MUFFIN_NO_SHADOWS=1
@kokbira Did you even look properly?
$ rpm -qf '/etc/environment'
setup-2.12.1-1.fc29.noarch
Short answer:
Sorry every one!
When I installed Cinnamon on Fedora 29, I did not change Display Manager, that was Gdm.
I have heard that Cinnamon appears to do not work well with other Display Manager than Lightdm.
So I changed it to Lighdm on Monday and ♪♫♬everything is going alright, don't worry about a thing ♪♫♬ ;)
Detailed answer:
I was confused with the issue, because when I used Linux Mint 19 Cinnamon that shadow issue happened and without knowing solution I survived with it.
But some other system crashes let me to use Fedora 29. And other system crashes later, I decided to change Gnome to Cinnamon on Fedora, and so I become a happier officer except for the display issues.
That display issues were forcing me to login system with only VGA display turned on and only after that I would turn on the DisplayPort display, elsewhere I cannot see menus, toolbars etc. of desktop or windows. Also, after the logon on that way, the wallpaper of VGA display became blinking and also that shadow issues happened together. So I thought the root cause was the same of that shadow issue, but only Monday I saw that is was a Cinnamon-only-works-well-with-Lightdm-issue.
After I fixed my issues using Lightdm substitution, I saw that MUFFIN_NO_SHADOWS=1 on a created /etc/environment only with that clause worked, but removing limits from a window to other ones. So I do MUFFIN_NO_SHADOWS=0 and the same happened. So I remove that clause and all is ok. Thanks!
Hi All, is there an easy-ish fix for this? I'm new to linux mint cinnamon and have managed some simple terminal commands, and have my windows looking and behaving as I want, with the exception of the removal of the shade. Same as the OP - I prefer the real estate on my small screen rather than a band telling me the title of the webpage i am on. Any easy way to get rid of it? I saw the comment above which mentions "root" in the command... not sure if i should be messing with those settings as a newbie.
