COSMIC 1.2 Arrives With AVIF Wallpapers, Wayland Fixes, and Smoother Intel GPU Support

by Geth Author

System76 shipped COSMIC Epoch 1.2.0 on June 30, 2026 — the second stable update to its all-Rust, Wayland-native desktop environment since the 1.0 release last year. This update is lighter on headline features than 1.1 was, but it addresses some of the most persistent rough edges users have reported: compositor flickering, Intel GPU compatibility problems, and fragile archive handling in the file manager.

AVIF Wallpapers, Finally

The most visible addition is AVIF wallpaper support in cosmic-bg, COSMIC's background daemon. AVIF is the image format derived from the AV1 video codec — it typically compresses 30–50% smaller than equivalent-quality WebP files and considerably better than JPEG, without the quality loss visible at high compression ratios. For a desktop background daemon, this means sharper wallpapers at smaller file sizes, with better color depth support for wide-gamut displays.

The practical benefit is modest for most users, but it's a meaningful capability gap closure. GNOME has supported AVIF wallpapers since 46, and KDE Plasma added it in 6.3. COSMIC catching up removes one reason photographers and designers keeping high-quality images had to transcode before using them as wallpapers.

Compositor Fixes That Actually Matter

The bigger reliability story is in the compositor. COSMIC 1.2 fixes workspace overview flickering — a visible glitch that appeared when switching between workspaces — and addresses a separate flickering issue in COSMIC Launcher, the application search interface that opens on the Super key. Both bugs were cosmetically distracting and had appeared in user reports since 1.0.

Newer Intel integrated GPUs also get better support. COSMIC's Wayland compositor had rendering artifacts on Intel Arc and Xe graphics hardware, stemming from assumptions in the rendering pipeline that didn't match Intel's more recent driver behavior. The 1.2 release adjusts these assumptions, improving compatibility with 12th and 13th generation Intel hardware that's common in laptops currently in the market.

File Manager and Application Reliability

COSMIC Files — the Rust-native file manager — receives two meaningful fixes. Archive extraction, which previously crashed on certain compressed file payloads (particularly multi-part archives and some zip files with non-standard metadata), is now more robust. The Trash folder also gains a proper folder preview, so you can see what's inside a trashed directory without restoring it first.

A long-standing issue where COSMIC Monitor — the system monitor app introduced in 1.1 — was missing application icons in its process list is also resolved. The fix involves correcting how COSMIC Monitor queries the application icon theme, which had been failing silently for apps installed outside the standard XDG application directories.

Where COSMIC Is Heading

System76 has published a roadmap for Epoch 2 and 3, the next major phases of COSMIC development. Epoch 2 targets deeper system integration — better suspend/resume behavior, improved multi-monitor hotplugging, and a COSMIC-native display manager to replace the current SDDM dependency. Epoch 3 is more speculative but includes a redesigned settings architecture and first-class support for adaptive themes that respond to time of day and ambient light.

For current Pop!_OS users and anyone running COSMIC on Arch, NixOS, or Fedora via community packages, 1.2 is worth updating to for the compositor fixes alone. There are no breaking changes, and the update path is straightforward through the standard package manager on supported distributions.
