Hello,

I've had a really strange and specific issue while using the COSMIC settings app where changing the display position specifically on my secondary ASUS VG249 monitor would set the refresh rate of the monitor to 60hz even though it was already set to 144hz.

This seems to happen when constructing the cosmic-randr command to call. The command called sets only the position of the monitor which different monitors tend to handle differently. The low-level explanation is above me at the moment, but specifying the refresh rate explicitly in the constructed cosmic-randr command appears to fix the issue at best and does nothing at worst.

I thought that cosmic-randr was trying to select the refresh rate of the monitor's default mode, but that doesn't seem to hold on my TV as it's default mode is 3560x2560@60 (had it set to 2560x1440@120 in the demo) so in theory it should have set the refresh rate to 60, but that didn't happen. Any other ideas/theories are welcome!

Here's a demo of the issue along with a demo of the fixed build: https://github.com/user-attachments/assets/5ffa3d3d-a9c9-4e62-843d-a7af72be4061

Testers would be greatly appreciated if you're also seeing this issue yourself!

Should also fix the following quote within the description of the issue pop-os/cosmic-epoch#1540:

If you then click the offending monitor and try to reposition it, after the screen flashes black and comes back the refresh rate setting will have been changed back to 60 Hz.

This PR has made it so that the displays can't be re-positioned by dragging anymore. They snap back to where they started from.

This PR has made it so that the displays can't be re-positioned by dragging anymore. They snap back to where they started from.

Apologies for the delay, could you provide the version of cosmic-randr you have installed so I can reproduce your issue? Additionally, if you run cosmic-settings from this PR from the CLI, are there any error messages that appear when changing screen position?

Edit: I'm also interested in what refresh rate your affected monitor is set to.

This is what I see when I run cosmic-settings from the terminal:

and the cosmic-randr version is:

@jacobktm Thank you, that was very helpful!

I suspect cosmic-randr is rounding the refresh rate to the nearest whole integer while my patch is simply rounding up when passing the CLI flag. I'll investigate specifically how cosmic-randr interprets the refresh rate flag and get a patch in soon when I've got time.

mmstick · 2026-08-19T18:43:58Z


                task.arg("mode")
                    .arg("--refresh")
                    .arg(format!("{}.{:03}", rate / 1000, rate % 1000))


We use integer math for the refresh rate, like so

NotYourAlejandro · 2026-08-20T00:21:38Z

Whoops, I thought I saw cosmic-randr accept only whole integer refresh rates, but I must've tested that wrong. Especially as that was how it was done directly below that.

@jacobktm Can you give it another shot?
