gnome-vrr VS gtk3-mushrooms

https://copr.fedorainfracloud.org/coprs/kylegospo/gnome-vrr/ :

  gsettings set org.gnome.mutter experimental-features "['variable-refresh-rate']"

This probably isn't what you're looking for, but by enabling this: https://copr.fedorainfracloud.org/coprs/kylegospo/gnome-vrr/ you can get vrr/vsync on Wayland for gnome, it can cause flickering but otherwise it's pretty good and got rid of any tearing and stuttering for me.

You can grab the patch from https://github.com/KyleGospo/gnome-vrr and build it.

Based on the comments in the AUR repo, I'd assume that the maintainer still invests time trying to update mutter-vrr. There seems to be a non-trivial issue when rebasing on Gnome 44, but I'm not able to assess how complex the problem actually is. (https://github.com/KyleGospo/gnome-vrr/issues/5)

Currently you can either use a Wayland DE that supports VRR, I know KDE has support for it, or use the gnome-vrr copr or build it yourself from his GitHub.

For fedora you can use https://copr.fedorainfracloud.org/coprs/kylegospo/gnome-vrr/

Just wanted to share my updated PKGBUILD to enable VRR in Gnome 43.2. The original author has no time to update his AUR package it seems so i updated it myself with the sources from the Fedora COPR.

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.
