I want to use the Shift key for a different window snapping tool, so this behaviour annoys me. I can’t find any setting or documentation for this, nor is it listed on any keybind list.
Tested on a fresh install. Linux Mint 22.2 Cinnamon Cinnamon Version 6.4.8
The extension for fancy window snapping: https://github.com/BasGeertsema/fancytiles
It’s a perfect alternative to FancyZones on Windows and works well when set to a different keybind.
I can confirm this behavior on my machine. And after a (far too) long internet search, I think it might be connected to this Muffin bug report from 2023.
I checked every single setting window and tab and scoured the gsettings with dconf editor and as far as I can tell, there is no way to disable this strange window snapping behavior when dragging a window with SHIFT held down.
Of course, the fact that people keep confusing snapping with tiling did not help in my search.
