gtk3-nocsd VS gtk3-mushrooms

After gtk3, window decorations are not a thing in gtk apps. The gtk theme is used to draw the elements. (Read client side decorations for better idea). You have to depend on 3rd party tools to restore window decorations, like this one. Don't know how well it works now, or even works with gtk 4, since i tried it way back and it has not seen any updates for years.

It's incredibly hacky, doesn't work on GTK4 apps, and only functions when using X11, but if those aren't deal breakers for you, than gtk3-nocsd might be what you're looking for. It forces GTK3 applications to use the same system side decorations that other applications do.

OK then. I think you want the more typical version of things. Stop Appearance and the like looking that way. The best option currently is this. I don't know what distro you're using so I can't say how you would install it exactly, sure you can figure that out.

You can try asking a question on the developer's site - https://github.com/PCMan/gtk3-nocsd/issues

I managed to remove them with this script: https://github.com/PCMan/gtk3-nocsd

gtk3-nocsd can help with this

It's not a Gtk style. It's a plugin/hack you need to install externally. https://github.com/PCMan/gtk3-nocsd

It is not about KDE/Breeze, from what I have read, the issue is with GTK(3.) One fix, not 100%, but almost pefect fix is to switch out GTK3 with GTK3-Classic.

GTK3 does indeed suck. That's why I run it with these patches.

Unfortunately they also lost tons of functionality in the process. The fact that typing on a file picker starts a recursive search instead of simply jumping to the file/folder with the prefix you typed, is nothing short of hilarious.

Gtk-classic is the only thing that keeps me sane https://github.com/lah7/gtk3-classic

The KDE Server-Side Decoration is also really powerful, allowing easy Maximize Horizontally/Vertically, window shading/hiding, and moving windows between virtual desktop/workspace, all while being able to be hidden when maximized for that extra screen space when I'm on my old 768p laptop and why I use gtk3-classic to get that SSD. Also, Window Rules -- they're very, very handy to get windows and apps to start and behave in a certain way by default.

I highly recommend gtk3-classic.

It's a bug when it stalls out your computer for 2-3 seconds because the file picker is doing a recursive search through all of your files.

Luckily, the patches that fix this (along with some other bugs and anti-features) are actively maintained by community members, despite being ignored by the GNOME project.

gtk3-classic will move them out of the titlebar, but if you want them completely gone you're better off switching to applications that haven't fully embraced CSDs like Gedit.

The GTK3 filechooser is the reason I switched to gtk3-classic.

Use gtk3-classic.
