Does this panel have a fixed custom size? Or is it in "fit contents" mode? (In reply to Nate Graham from comment #1) > Does this panel have a fixed custom size? Or is it in "fit contents" mode? It is in "Fit Content" mode If the panel is in "Fit contents" mode, then can you help me understand why you're expecting it to change size when it moves to a different screen? Is it because you've configured it to show only tasks from the active screen, and the screen it moved to has a different number of open windows on it?

Prior to updating KDE, "Fit Content" would automatically resize the taskbar to fit my Samsung G5, but after the update it no longer resizes the taskbar under the same settings, but instead stays the same size as my 2nd monitor, which is a much smaller resolution. "Fit Content" is supposed to fit the content in the panel; it isn't supposed to reflect anything about the monitor geometry, and never has (or if it did, that was a bug). Perhaps a screen recording would help to clarify whether there's a bug here, or whether the behavior is unexpected but intentional. Can you make one? A phone video would work too, if it's not feasible to do a screen recording due to the need to change the screen setup. Created attachment 181037 [details]

Thanks for the screen recording. Are you absolutely sure that panel is using "fit content" mode? If so, it seems to be too wide no matter which screen it's on; it isn't fitting the content in either case in your screen recording. Are you sure it's not actually in "Custom" mode?

I wonder if there are widgets on the panel causing it to have a minimum size that's too high, and that minimum size just so happens to make the panel roughly the width of the smaller monitor, obscuring the true issue by making it seem like a "fill width" panel. Could you check that? It might also be helpful to create a new fit-content panel with the default widgets and see if the issue affects that panel too?

Fit-Width does make it properly scale the taskbar between displays and looks identical to how fit-content used to work prior to the update. I included a new video to show that altering the scale or resolution of the display and reverting the change does make the fit-content update properly to fit the entirety of the display. Thank you, that's very helpful. In that case, I'm pretty sure I understand what's going on: your original fit-content panel just happens to have the same appearance of a fill-width panel due to how much stuff is on it. When it's on a different screen with more space available, it can limit its width as it would prefer. If there is a bug here, it's why that panel takes up so much space on the smaller screen. It looks like there's a bunch of empty space in the middle that should be collapsing. So I suspect some of the widgets on the panel are taking up more space than they need to. Can you figure out which widgets are to blame here?

Can you figure out which widgets are > to blame here? the only widgets I have manually added was the ram, cpu, and gpu usage monitors. But after tweaking I do suspect that its the Panel Spacer widget not properly scaling when in Fit-Content? Well, if you have a spacer in there, its reason for existing is to take up space. :) Can you share a screenshot of how the panel looks on the large screen if you remove all the spacers from it?

This is what my taskbar looks like with spacers removed. OK great, that looks normal. So I think this is *literally* not a bug, then. :) Everything works as expected, and your specific combination of panel settings made you think it was a bug, but it wasn't!

The spacer widget does not change size when switching between monitors, and it didn't behave like that prior to the update. But if its not a bug then sorry for wasting your time To my knowledge it's supposed to work like that, yeah. If it didn't before, that was probably a bug that got fixed! |
Created attachment 181012 [details] Taskbar in bugged state For context, I have two monitors. Samsung G5, 165hz 3440x1440 (Primary Display) Acer V176L, 75hz 1280x1024 The Samsung G5 powers off the monitor when I press the Power Button The Acer V176L puts the display to sleep when I press the Power Button When I turn off both displays, It makes the Acer V176L the Primary Display as the Samsung G5 is powered off and unable to be recognized by my system. The bug only started appearing after updating my system on May 5th 2025 I started to experience a bug where when I power on my Samsung G5 and when my system switching it to be the Primary Display, The task bar does not properly resize to fit the change in resolution but instead stays the same size as it was on the Acer V176L. The only manual fix I am aware of is to change the resolution or scale of the display then revert the change to make the taskbar properly resize to fit the entirety of the screen. Attached file is the task bar as the bug is active.
