SUMMARY I didnt know where to report it, so feel free to forward it. In Plasma 5.16 the Icons KCM was updated. The new update breaks something fundamental for Panels. As was discussed in previous plasma versions there should be a way for applets in panels to remain in CompactRepresentation. The conclusion was that the "Panel Icon Size" would be used for this. Unfortunately the new KCM sets a maximum value for this at 64px. This is NOT enough because for sizes > 64px it allows applets in panels to have a FullRepresentation. A good example why this is not enough is the Latte case. When an applet is zoomed through parabolic effect its size could even reach 256px. So when the FolderView applet is zoomed in Latte it changes from CompactRepresentation to FullRepresentation and vice versa. a user reported that manually this value can be altered with: "kwriteconfig5 --group PanelIcons --key Size 256" In my opinion the least that Plasma must provide to users is values up to 512px from Plasma Icon size. This should benefit also the plasma panels users. I will attach also a screenshot of the in-question KCM

That depends on the icon theme. With Breeze and Oxygen I get 256 pixels as maximum allowed size. I found there is a bug that when the icon theme specifies no sizes, the dialog doesn't allow choosing any size, but there's no hardcoded limit of 64 in the settings module.

I understand, then the maximum should not depend on the icon theme. Plasma is now using this value to define the limit of changing between CompactRepresentation and FullRepresentation and that is independent of the icon theme
If you have a pixmap-based theme, your icons blowing up to 512px could be undesirable? I wouldn't have expected Latte to actually change the widget geometries on the fly.

You icons will never blow up to 512px. because the applet thickness in a panel is totally dependent to the panel thickness. If your panel is 92px. you will get 92px. icons even though you have set 512px. The 512px. is just the MAXIMUM. In plasma panels that translates as following. If the user chooses maximum 64px. and the panel has 100px height then the applets in it will look as 64px with top and bottom margins of 18px AS LONG AS they never change to Full Representation. If these applets can change to Full Representation when they are in a panel the for panel thickness >64px they look as if they are in the desktop, this is the Folder View case. Concerning Latte, Latte is changing the applet geometry on the fly BUT the problem is that the FOLDEERVIEW looks as icon when is NOT zoomed and during the ZOOMING changes to FULL REPRESENTATION. Totally broken experience. If you want to reproduce in a plasma panel you can do the following. 1. Objective, to force the Folder View applet to look as a Single icon whenever in a panel 2. Set the in question option to 64px. 3. Grow the panel thickness above 64px. it does not remain to icon and the users do not have an option to increase the maximum above 64px.

Operating System: EndeavourOS KDE Plasma Version: 5.22.5 KDE Frameworks Version: 5.86.0 Qt Version: 5.15.2 Kernel Version: 5.14.8-arch1-1 (64-bit) Graphics Platform: X11 Processors: 4 × Intel® Core™ i5-2500K CPU @ 3.30GHz Memory: 31.3 GiB of RAM Graphics Processor: NV137 I have my panels (Bottom, right and left; I like panels!) set to a height/width of 148px to accommodate 128px Icons (4K screen). some of the Icons are ones I made, both .png @ 128 and svg scalable, and some are Breeze Dark Icons and they are all scaled to 48px. In System Settings> Appearance> Icons> [Configure Icon Sizes]> I have diiferent max sizes than I remember the defaults to have been a while back, as well as had them set larger and displaying properly, but some, or all just all changed a while back, the max I can set are: Toolbar = 256 (set at 64) Main Toolbar =
Oops! lets finish: ICONS MAX Set to Toolbar = 256 64 Main Toolbar = 48 48 (may want to try 64 and see what it looks like) Small Icons = 48 32 Panel = 48 48 (I want 128) Dialogs = 256 64 So whoever has 64px panel icons is one size better than I have! )<: So there is definitely something strange happening. I also cannot change icons at all in panels anymore, because after choosing one in Properties the [OK] button stays grayed out, and ticking it does nothing, but changing the ones with desktop files in the file itself works, accept they are still only 48px. If this helps: my panels are all set to auto hide. My taskbar Icons and widgets, all but the taskbar resize with panel size changes, but not the panel Icons themselves (That's backward!) I made 512 Icons years ago (png's) in anticipations of screens reaching insane resolutions! Now I make them as svg's. Thanks for your time.
The Panel icon size was removed a few releases ago, so this is effectively fixed... or at least no longer possible as a thing that can happen.
