A System76 scheduled the release of beta version of Pop! OS 24.04 September 25, 2025. This version introduces the most significant change in distribution history: replacement of the environment GNOME on his own desktop, COSMIC, developed internally.
For professionals who rely on systems Linux for audiovisual production, this update deserves a careful analysis. The stability and performance of the operating system are the basis of any workflow, and this new version of Pop!_ OS, standard system used in Movy Audiovisual, the producer associated with Cine Linux, needs to be evaluated for its technical merits.
The basis of COSMIC: Rust's benefits to a desktop
System76's most impactful decision was to build COSMIC with the programming language Rust. Unlike traditional environments written in C++Rust offers a key advantage: memory safety guaranteed in build time.
For the end user, especially in a production environment, this translates into a much greater resilience to crashes. Segmentation errors and memory management-related bugs that can freeze or drop an entire desktop environment during a heavy rendering or when managing multiple assets are drastically minimized. The promise is a work environment with greater stability and predictability, where the desktop itself becomes a more reliable layer of abstraction between hardware and creative software.
In addition, the COSMIC architecture, which uses the toolkit Iced (also based on Rust), it was designed for parallelism, taking advantage more efficiently of the multiple cores of modern processors. The graphical interface should no longer compete for features with an export process in DaVinci Solves or a simulation in Blender, because the task delegation is managed smarter.
The transition to Wayland and the impact on image quality
Pop! OS 24.04 will make the final transition to the Wayland as your graphical server protocol. Although Wayland is not a novelty in the Linux world, its implementation together with a new DE is a critical point of assessment.

The Wayland principle that "each frame is perfect" (every frame is perfect) naturally eliminates the screen tear, a visual artifact that can be distracting during real-time video playback in the editor. For video professionals, this means a cleaner and more accurate visual representation of the content, without the need for external composers or complex settings.
The Wayland architecture also opens doors to a more robust color management and centralised, a crucial aspect for colorists and photographers. Although the final implementation needs to be tested, the potential for a consistent color pipeline from operating system to application is one of the most significant promises.
However, the transition poses challenges. Compatibility with screen capture software, remote access tools and especially interaction with specific peripherals such as scanning tables and color calibration probes will need to be rigorously tested. The community should be alert to see if the implementation of Wayland in COSMIC has reached the necessary maturity for production environments that do not admit failures.
Kernel Optimizations and Task Scheduler
Historically, one of Pop's differentials!_ OS is your process scheduler (scheduler), which prioritizes the focus window, ensuring that the active application receives most of the CPU resources. For audio production, this is vital because may reduce the occurrence of xruns (audio buffer failures) in DAWs as Ardour or Reaper under heavy load of plugins. In the video context, it ensures a more responsive editing interface.
The expectation is that Pop!_OS 24.04 will maintain and enhance this behavior. Beta analysis should focus on how the new DE interacts with the scheduler and whether this performance optimization remains a practical differential in long-term tasks and intensive CPU use.
Critical Points for Beta Evaluation
The arrival of beta on September 25 will be an opportunity to validate System76's promises. In our tests at Movy Audiovisual, we will focus on the following technical aspects:
- PipeWire audio and performance latency: How does the new environment integrate with PipeWire? Does round-trip latency for recording and monitoring audio with professional interfaces stay low?
- Graphical performance and VRAM management: Is COSMIC lighter or heavier in terms of video memory consumption compared to previous GNOME implementation? How does it behave with multiple 4K monitors and applications that require high VRAM allocation?
- Hardware compatibility: Pop's recognized ease!_ The NVIDIA drivers (including CUDA and NVENC) were transported without regressions to the new base? Professional periféricos will work immediately?
- Stability under stress: Will the system remain stable after hours of continuous work, with multiple heavy software open and during rendering processes that use 100% CPU and GPU? Will Rust's memory security prove itself in practice?
In short, Pop!_ OS 24.04 Cosmic is not just an aesthetic update. It is a fundamental reengineering that has the potential to offer a more solid and performative basis for content creators. The beta period will be decisive to determine whether this promise will become a reliable production tool.
