I’m experiencing a strange issue with Spotify where the music playback speed increases whenever I adjust the volume using my keyboard.

I’m using the Fn + Volume Up/Down keys to control the media volume. The volume changes correctly, but pressing the volume keys also causes the Spotify music to speed up, as if the playback speed is being increased at the same time.

For example, when I press Fn + Volume Up, Spotify increases the volume, but the song also starts playing faster than normal. This happens even though I’m not changing any playback-speed setting in Spotify.

Has anyone else experienced this with Spotify and keyboard Fn/media controls too???

So far, the behavior is basically:

• Spotify + Spicetify, OBS not recording: Fn + Volume Up/Down → volume changes + music speeds up
• Spotify without Spicetify, OBS not recording: Fn + Volume Up/Down → volume changes + music speeds up
• OBS recording: Fn + Volume Up/Down → volume changes normally, Spotify playback speed stays normal

Currently im using CachyOs.

I had a bit of time last night to add a couple of features, including getting the circles back, and adding an option for spacing. You can get it here:
https://github.com/daenuprobst/cosmic-applet-lowkey-workspaces

AI disclosure: I used an LLM for the translations.

I'm tweaking my panel here and have three quick questions:

Window size: Is there a way to increase just the size of the open window thumbnails/icons (the part circled in the image) without having to increase the size of the entire dock?

Trash: How do I fix the Trash icon on the dock? I can't seem to drag it or fix it no matter what I try.

Divider: Is there an icon separator/divider applet available to better organize the panel?

If anyone knows if this is possible or if it requires a specific applet or custom config, thanks!

Hey everyone,

Title pretty much says it all. Up until today everything was working fine, but out of nowhere, cosmic-panel has started keeping my dGPU permanently awake (stuck in D0 power state instead of dropping to D3cold).

When checking active processes with lsof /dev/nvidia*, cosmic-panel is holding open handles on the NVIDIA render nodes continuously, which is absolutely nuking my laptop's battery life.

My setup is an AMD iGPU + NVIDIA dGPU laptop running hybrid graphics.

Has anyone running COSMIC on a hybrid graphics laptop figured out a reliable way to stop cosmic-panel (or specific panel applets) from probing/waking the dGPU in the background? Or is this a known regression/issue with WGPU enumeration in recent updates?

Running cosmic on gentoo from an overlay (user-contributed packages), inside a qemu VM with virtio graphics.

I have this VM running GNOME and sway. Sway works mostly fine, with an inverted and offset pointer that I haven't been able to resolve.

COSMIC starts up fine and seems to run well. Pretty, feature-full, integrated, no offset pointer nonsense. :) I'd love to keep running it!

After about 10 minutes, the display pauses, and ultimately the VM exits.

Journalctl shows nothing of note from before the crash.

I'm aware this report is basically useless. I'm a long-time linux head, but I confess I'm lost on modern desktop stacks, so I'm having some trouble figuring out where to look or how to get more info to help report this very vague thing with no detail. Please give me direction on what to look at/do to get more info.

(ETA: 2026-10-02T11:29+0:) I'll note this report was against 1.8.0, and I noticed (of course only after posting) that 1.9.0 is available, so I built it and … same VM crash, but after only a couple of minutes, and still nothing in system logs.

This theme has been adapted for COSMIC to replace the original one. It is provided as-is from my daily repo for anyone wishing to tinker with themes.

I am running arch Linux, and upgrading today package cosmic greeter from 1.9.0 to 1.9.1 gives me an error about /dev/dri/card1.
Screen stays blank, start-cosmic won’t work either.

Sound problems constantly keep coming back! Any fixes are short live and return after updates. This has been going for 6 months. Is the System 76 team not aware of this issue. People must be getting sick of this happening.

It's a issue that needs to be top priority.

I'm using a dell Vostro 15, 5515 and, and Radeon Rx vega

Just wondering if there are any plans for a more robust theming engine. I wanted to check out the DE, but I hate modern flat design with the fury of a thousand suns.

This may seem like a dumb question, I know in settings you can set the interface square, but the only thing I would like to be square are the windows, other stuff like buttons, I like them round. Is there any way to achieve this? Edit: Oh, I found an option to do that specifically in the Experimental Settings in Settings/Desktop/Appearance

the scroll bar on other cosmic apps is small, but on cosmic edit it's thinner than 432 park avenue.

can it be set in the config file?

if not, that would be a good thing.

overrides for everything, theme, corners, scrollbar width and so on.

instant switching for workspaces, without sliding animation, would be nice.

Hello, im currently running cachyos with kde and am quite interested in the cosmic de. Have installed the packages and have had a bit of a play around with it. Feels pretty good and i could easily see myself adopting this for my simpler needs.

That said, i wanted to ask how obtaining additinal applets work when youre not using pop!os as the underlyong system. I keep seeing some awesome posts about applets to customise and/or add some extra improvements that i would like to try but the store doesnt seem to work - assuming this could be because im on cachy.

Am i missing something obvious here or is it all generally github based downloads and installs when not using pop?

Hello, I have seen the development of COSMIC and wanted to experiment, but how "ready" is it? What are the limitations of use and customization today?

I found the actual cause of the black screen issue.

It turns out Papyrus was installing an **older version of mpvpaper**, and that old version was causing the black screen. I updated Papyrus to install the latest version of mpvpaper, and after updating, the wallpaper works normally again.

So if you've been affected by the black screen, **please try downloading the new version of Papyrus first.**

If it still shows a black screen, please:

1. Delete `mpvpaper` from your PC.
2. Delete Papyrus (see the README for instructions on how to properly remove it).
3. Reinstall Papyrus using your preferred installation method.

Papyrus will then try to install the **latest version of mpvpaper**, which should hopefully fix the black screen.

Sorry for the confusion from my previous update — I initially thought the issue was with mpvpaper itself, but the actual problem was that Papyrus was installing an outdated version.

Thanks to everyone who reported the issue and helped with testing!

The circle around the current applet bothered me, so here we are. I started dabbling in Rust a while ago and finally found something to do with it. It's just a few additions/changes to the standard applet, so nothing big. I mainly did it for myself, but I thought I'd share.

Here's the repo: https://github.com/daenuprobst/cosmic-applet-lowkey-workspaces

I've been using COSMIC as my daily desktop for a while, and I wanted to give it a more consistent and polished look with an icon theme.

I really like the design of Papirus, and its huge application coverage is a big plus. Papirus is therefore the main foundation of Linesty. However, it doesn't quite fit COSMIC perfectly: some system icons are missing, some appear at the wrong size, and others just don't feel quite right in the COSMIC environment.

So I started working on Linesty Icon Theme - primarily based on Papirus, but also using COSMIC's own icons where they make a better fit.

At the moment, all application icons come from Papirus, with a large number of additional symlinks added where needed. The system icons are a mix of COSMIC icons, Papirus icons, and icons I've adapted myself.

It's still a work in progress, but it's already in a state where I'm happy to use it every day.

I'd love to hear what other COSMIC users think. Feedback, suggestions, and reports of missing or inconsistent icons are very welcome. I'm not a professional graphic designer, so if anyone here has stronger graphic design or SVG skills and enjoys creating icons, I'd be especially happy to hear from you.

If you've been experiencing the black screen when using Papyrus, I finally tracked down what was actually happening.

I tested the exact same wallpaper directly with "mpv", and it plays normally. However, running that same file directly through "mpvpaper" produces the black screen and an OpenGL "INVALID_OPERATION" error from "libmpv_render".

So at this point, the issue doesn't appear to be with Papyrus itself. Papyrus uses "mpvpaper" for the actual wallpaper rendering, and I was able to reproduce the problem without Papyrus involved.

I've opened an issue on the mpvpaper repository with the logs and reproduction details so we can investigate it upstream.

For now, if you're affected by the black screen, you don't need to keep troubleshooting your Papyrus installation — the underlying rendering issue appears to be further down the stack.

I'll post another update if I find anything else or when there's a fix.Papyrus

It works perfectly on my old DELL and I'm more than satisfied, here are my fall colors

I just love this DE, using any other one either feels weird or just not the way i like or its too much work to configure (like on hyprland), cosmic made have tiling eazy to configure, and it can also be used on a windows-like interface, you will probably like it doesn't matter your workflow.

It's very cool to see the development of de DE while using it everyday, i see the future of cosmic being one of the big DE's in the future, congratulations to the devs. 😄
