Seven months in, System76’s COSMIC desktop is doing something rare: actually shipping. Version 1.3 just landed with 186 contributors, 16,000+ merged pull requests, and a feature list that’s starting to make other Linux desktops look slow.
The headline grab is dual-monitor workspace handling. On KDE, switching workspaces moves both monitors together. On COSMIC, each monitor gets its own independent workspace. It sounds like a small thing until you’ve lived without it. One user who switched from KDE put it plainly: this is the feature KDE should have shipped with. You can also run tiling mode on one monitor while keeping the other in floating mode, which is the kind of workflow flexibility that usually requires a dedicated tiling WM and a lot of config file archaeology.
The 1.3 release also added frosted glass effects with granular controls per panel, applet, and window. There’s a new system monitor with CPU, memory, GPU, disk, and network views. The compositor gained window shadows and sticky windows. COSMIC Store now handles rpm-ostree and RPM files. The terminal, file manager, and media player all got meaningful updates, not just version bumps.
Under the hood, COSMIC Text is written in pure Rust and just gained ellipsis support used across the whole desktop. The compositor added pointer constraints (relevant for gaming) and support for multiple fullscreen windows per workspace.
The honest caveat: COSMIC is still rough in places. It’s a 1.x release on a desktop that’s been in development for years, and the polish gap versus GNOME or KDE is real in spots. But the trajectory is hard to argue with. Most Linux desktop projects spend years debating architecture. COSMIC is merging PRs.
The dual-monitor story alone is pulling in converts. When your differentiating feature is something users describe as “should have existed years ago,” that’s a decent sign you’re building the right thing.

Trends

System76's COSMIC desktop environment reached version 1.3 with 186 contributors and 16,000+ merged pull requests. The standout feature is per-monitor independent workspace management, a long-requested capability that KDE and GNOME still lack. Other additions include mixed tiling/floating mode across monitors, frosted glass effects with per-panel controls, a new system monitor, window shadows, sticky windows, rpm-ostree support in COSMIC Store, and pointer constraints for gaming. COSMIC Text, written in pure Rust, gained ellipsis support used desktop-wide. While polish gaps versus GNOME and KDE remain, the project's shipping velocity is notable compared to the slower pace of competing desktop environments.

COSMIC DE is quietly shipping features KDE and GNOME still argue about

Now if they could just stop shipping kernel’s that brick those stupid onboard AMD GPU’s when you also have a dedicated Nvidia GPU I’d actually be happy, but hey, they can keep working on ui polish.
