I like to snap my windows in GNOME to one side of the display or the other and to snap them into one of the corners of the display. I can do this by dragging the window using the mouse or by pressing the Super key with a direction key.
I had done this for years. But recently, every time I drag any window to the edge of my display and let it snap into position, I immediately then get a window switcher popup, basically the same popup I'd see if I were switching windows by pressing the Alt and Tab keys.
How can I stop this popup from appearing after I snap a window?
In case it helps, I use Tiling Assistant together with Just Perfection (the latter is used to put the panel with the clock to the bottom of the display).
