Disable extra buttons on window titlebars

[MinePro120]

Hello. I've searched everywhere for this, but apparently I can't find what I'm looking for. GNOME apps (like gnome-calendar, gnome-calculator, dconf-editor etc.), have some extra buttons (other than minimize, maximize and close) on their windows' title bars, as shown in the picture below (which makes me hate GNOME for their poor decisions even more). Is there any way to disable them? I've looked into dconf settings and gnome-tweaks (even though I'm on cinnamon) with no luck. nemo seems to have the same kind of buttons as gnome-calendar, but they're not on the title bar (why would anyone want the title bar to be so thick and of inconsistent width? ).

I "fixed" it using Sway LOL -- "You can't double my buttons if I don't have buttons"
/trollmode off

I dont' really have a solution, all I know is that it is a known problem and it looks like it's an interaction between Gnome applications and the desktop environment, extensions and customizations in particular.

Gnome is redesigning the way things look and work (again, and again), I think the rationale behind those title bars, besides the "tablet look" and outdoing Apple, is to make use of that otherwise usually wasted horizontal space -- at the expense of vertical space, inconsistent user interfaces for years to come, and incompatibilities like this one.

It seems to me that some of the newer applications draw their own titles to be able to place extra buttons in there, while normally that is a task of the window manager, so unless the wm is aware of that, there are two title bars. But I could be wrong here, not that I really investigated much.
All I can say, in Sway there are no title bars (by default, they can be enabled) and some Gnome apps still display their own.
Another funny thing: try placing the window buttons on the left, you'll see some applications with buttons in the middle of the title bar, those with a left panel like the Gnome settings of all things.

I experience no double title bars, is it possible what you were confused by the 2 images I put close together? (I added some spaces now)

[meanruse]

Yep I've been confused by that. It really looked like those double bars I was talking about.

So, you'd like to have "normal" title bars without the extra buttons?
Got this link from GNOME - ArchWiki -- the first place where to look for answers about all things Arch, and possibly the best written documentation on the interwebs.
Not sure it's what you are looking for but sounds like it should.

[MinePro120]

Yes, that's what I want to achieve. I consulted the Arch wiki before posting, but still, I don't see anything relevant. I'm not on GNOME, how could I switch to GNOME-Classic? That's gotta have something to do with muffin WM right?

[meanruse]

I hoped some of that stuff could be applicable, and sorry for the RTFM -- how could I know.
I'm not on Gnome either, and looks like I can't be of much help so... I just sneak away

[dalto]

It is because gnome applications are client-side decorated so they draw their own.

[Naman]

Hi,

first of all, you have customized themes, and they are not the default one. So I have no idea what you have modified and what not.
Nemo should look like this by default

Also, these buttons can be modified under edit>preferences>toolbar
Also, you can disable toolbar altogether in view>Main Toolbar checkbox

Wait a minute, how did you install cinnamon? On top of Gnome edition? Post your output of garuda-inxi

[MinePro120]

No, I'm just using the Cinnamon edition, with another theme (Nordic). I don't want to change nemo's behaviour. I want to change the behaviour of all gnome apps adding menus and buttons to title bars.

Here is how gnome-calender looks like here

And it is how it should look like by default, according to gnome. For example, see
https://wiki.gnome.org/Apps/Calendar

I guess, you should ask Gnome devs the reason for this.

[MinePro120]

Well, as @dalto said, they seem to have a mind of their own... I guess I can't change that.

[Naman]

Well, tbh, I like it this way, because it looks slicker this way.
Just a personnel preference though.
