Top panel does not stretch across wide monitor until refresh rate is changed manually

Sorry if this has already been discussed elsewhere and I hope this is the correct place to bring up such an issue, but I couldn’t find it. I’m new to Bluefin, but have spent many years using other distros (mostly debian-based distros).

Context

I’m using a Dell 38" monitor with a resolution of 3840x1600. I’m using this in landscape mode and at a scale of 100%.

Issue

Whenever I restart the computer (also when I initially loaded up Bluefin for the first time) the top panel does not stretch all the way across the monitor. I can attach a screenshot if desired, but I’m not sure how to get the issue to occur without restarting again, and don’t think it’s probably that important to see.

Workaround

I can fix this issue (until the next restart) by going into the displays settings and changing the monitor’s refresh rate. The options are 59.99 Hz and 30.00 Hz and the monitor defaults to 59.99 Hz. When I switch to 30.00 Hz the issue is resolved. Then I switch back to 59.99 Hz and the issue is still resolved so it doesn’t seem to be tied to the lower refresh rate, but for some reason updating that does fix the issue until I restart again.

System Information

I’m on Bluefin stable (which is currently using Fedora 40).

Output when I run rpm-ostree status:

State: idle
AutomaticUpdates: stage; rpm-ostreed-automatic.timer: no runs since boot

I believe this is an issue with Blur my shell: bug on startup with multiple monitors with different resolutions · Issue #503 · aunetx/blur-my-shell · GitHub

You can either make it so the 2 monitors are not “levelled” in their placement settings (so one lower than the other slightly) or disable the extension entirely.

Example:
This will cause the issue:

This will not:

Hey, can you also list all the extensions you are using ?

Also, is it happening in those condition:

  1. Disable all GNOME extensions
  2. Shutdown (not reboot) your PC
  3. Boot it up again

?

@Matty_pixels so I tried to re-align the displays height like shown in the screenshot (not having the tops aligned) and still saw the issue.

@Malix I don’t see the issue if “blur my shell” extension is disabled. Powering off, then back on after had the same results.

The issue also disappears if I disable and then immediately re-enable the “blur my shell” extension.

Yeah, this is definitely an issue with blur my shell, the one I linked.
If your 2nd screen is vertical, there’s no solution either other than disabling the extension.

Okay, I appreciate you getting back to me.

I did see there is an issue on GH for them, so I’m sure this can just be closed. I didn’t realize that was for sure the issue when I originally added this.

Thanks for the help
