Created attachment 150221 [details] Comparison of screenshots of icons. SUMMARY In 5.24 and before, icons on "Icons-only Task Manager" were smaller, height-wise. STEPS TO REPRODUCE 1. Add a panel to the desktop 2. Add "Icons-only Task Manager" widget to the panel 3. Make the panel vertical 4. Open a bunch of apps, so that the widget is populated 5. Observe the icons on the widget OBSERVED RESULT Icons are too big, height-wise. See before and after on the attached image. EXPECTED RESULT Icons are smaller. See before and after on the attached image.

I'm afraid this was an intentional change. The "After" screenshot looks much better to my eyes; more padding around the icons helps to frame them and prevent the panel from turning into icon soup. It also provides larger click targets. If you'd prefer smaller icons or task manager buttons, you can make your panel narrower.

Re-opening since we're getting a lot of complaints about this, particularly for panels that are 38 or 40px in thickness or thicker (the exact value depends on the screen edge). In particular, at exactly 38 or 40px thickness, the icons are just enormous and nearly touch the edges of their bounding boxes. It just doesn't look good. This may conceptually be a tricky problem to solve though, since the change was intentional to allow the icons in Task Manager tasks to use the same margins as other panel widgets, so that all of the icons on your panel align. We'll need to see if we can resolve this visual issue without abandoning that effort.

Ah, I think I may see the issue. App icons (well, most icons) internally have their own margins between the icon itself and the bounding box it lives in, and those should be preserved in addition to the margins that the Task Manager adds in code. Looks like that's not happening.
Specifically, it looks like the icon is applying its own internal margin, but the Task Manager is completely ignoring the margin added by the panel, instead of fitting the icon box within it.
I also would like to contribute to this problem. I use KDE with 4k monitor, and since upgrade, icons have become too small. Before, when I adjusted panel size, Task Manager icons would decrease/increase accordingly, scaling smoothly, perfectly for my needs. Now, icons are fixed in size, and too small for me. I use 4K monitor, vertical panel of 256 size, with Task Manager. Icons are too small. https://i.imgur.com/Mqd4ZrC.png Can you please restore smooth icon sizing functionality, or introduce setting in Task Manager so I can set icon size?
Task Manager Icons having a maximum size that's too low, or icons not resizing smoothly, are different bugs. We will need additional bug reports for those--one per issue. If you'd like to contribute to fixing these issues, great, feel free! Merge requests can be submitted at https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/.

See > https://community.kde.org/Infrastructure/GitLab#Submitting_a_Merge_Request I'm sorry, I am not a developer. I just wish problem has been fixed and Task Manager behaves like before. Before update, I had panel with adjustable size and icons on Task Manager were scaling smoothly. Now, icons are fixed in size. Not scaling anymore, and too small to my preference. And no option to adjust icon size at all. Please resolve this issue, if possible, be reverting offending regression. Thank you.

Of course you do; so do I. :) To make that happen, someone needs to fix it. That's type of contribution that's helpful at this point. I'm looking into it, but could use some help. I can't find what part of the Task Manager icon code adds in the Panel margins; it's like it's missing. Maybe that's the problem lol
> I can't find what part of the Task Manager icon code adds in the Panel margins; it's like it's missing. Maybe that's the problem lol The change happened between plasma versions 5.24.4 and 5.25.3, so running a diff on the Task Manager code between those two versions should help identifying it.
Created attachment 151324 [details] 5.24 - nice large icons on 1440p Thought I'd add 3 screenshots. Here's FULLSCREEN screenshots. Look at how small the icons are no matter what I width I chose with 5.25. IMO it does not look better nor more practical. This comes from bug (https://bugs.kde.org/show_bug.cgi?id=455618)

Created attachment 151326 [details] 5.25 - No matter the width of panel icons stay small
This bug is still present in 5.26 - should I open a new bug report? KDE Panel still looks silly on HIDPI screens with X11. Have to constantly use 5.24.5 gets annoying.
Still not happy that this is said to be a duplicate 455618 as this subject wording implies the opposite "bigger" vs the icons actually not getting any bigger they are SO small on a hidpi screen it's not even useable. The largest they ever get on a vertical panel is with a width of 40. Anything wider than 40 and icons will never get bigger yet EVERYTHING else, correctly, does. Surely this is a quick fix? Set max icon size bigger?
