Created attachment 166426 [details] Screenshot examples SUMMARY The desktop Floating Panel on Plasma 6 unfloats as soon as a window is tiled nearby the panel if using tiling padding lower than 28 pixels. Same issue no matter if a vertical or horizontal panel is used and no matter what panel width is set. To keep the panel in floating mode we are required to use tiling padding of 28 pixels or more - which is undesirable and brings a huge gap size between windows. The floating panel typically uses a gap of 9 pixels from screen edges so I typically use a tiling window padding of exactly 9 pixels so that windows are perfectly visually aligned with the panel edges (unfloated) and the screen/desktop edges. This worked fine previously with Plasma 5. No longer works on Plasma 6. Please fix it. STEPS TO REPRODUCE 1. Enable System Setting > Window Management > Desktop Effects > Window Management > Tiling Editor (Meta+T); 2. (Meta+T) Set a Window Tiling Layout with padding of 27 pixels or lower (9 pixels in my case); 3. Tile any open window next to the panel and observe the panel unfloat. (screenshot example attached) OBSERVED RESULT The desktop Floating Panel on Plasma 6 unfloats as soon as a window is tiled nearby the panel if using tiling padding lower than 28 pixels. (screenshot example attached) EXPECTED RESULT The Panel should keep the floating mode *regardless* of the padding width set on the tiling layout. The Panel floating mode gap/padding next to any tiled windows should be exactly the same as the tiling padding width - as is on Plasma 5.

Small correction to the SUMMARY: - Where it reads: The floating panel typically uses a gap of 9 pixels from screen edges so I typically use a tiling window padding of exactly 9 pixels so that windows are perfectly visually aligned with the panel edges (unfloated)... - It should be read: The floating panel typically uses a gap of 9 pixels from screen edges so I use a tiling window padding of exactly 9 pixels so that windows are perfectly aligned visually with the panel edges (floating)...
Can reproduce the part where the panel defloats more than 12px away https://invent.kde.org/plasma/plasma-desktop/-/blob/master/desktoppackage/contents/views/Panel.qml?ref_type=heads#L115 The part about the panel defloating when a window is tiled nearby (closer than 12px in this case) is intentional, so I am going to change the title to better reflect the problem.
Thank you for the clarification. So I guess that design setting changed from the Plasma 5 panel then? Any reason why? In my use case seem lost functionality. I did a quick check on the code you have linked to. Assuming that there is a good and valid reason for that design change I would then question: 1. The panel floating mode seems to be designed with a default 8px gap distance from screen edges (and not 9px as I have mentioned on my report). Any chance that this 8px value can be used instead for the "property int defloatDistance"? That would potentially allow the use of an identical value of 8 px as minimal tiling window padding? 2. Ideally, we should be able to customise the panel floating gap distance from edges. Any chance for it? For those of us wo like to keep it simetrical/coherent we would then use the same value on the tiling window padding. And that gap/distance would be kept between the floating panel edge to any tiled window next to it.

The reason is written as a comment in that code. It avoids an issue (https://bugs.kde.org/show_bug.cgi?id=476743) with KWin's snap-to-panel behavior. > The panel floating mode seems to be designed with a default 8px gap distance from screen edges (and not 9px as I have mentioned on my report). Any chance that this 8px value can be used instead for the "property int defloatDistance"? That would potentially allow the use of an identical value of 8 px as minimal tiling window padding? I tested multiple values, including 8px. It wasn't enough, I found we needed a 12px distance to avoid the snap-to-panel behavior from activating. Other potential solutions can be investigated. Nate suggested disabling the snapping completely when in floating mode.
