Thank you! Sorry for the delay in getting back to you.
I’m not entirely sure about this. I’m currently working on fixing some general lag issues with the floating menus, but the window resizing itself usually triggers instantly for me.
The only thing that comes to mind is disabling the 'Activate Window Under Cursor Before Snapping' named trigger. That one runs an if condition that might be interrupting the resize action when the swipe gesture is too quick.
Let me know if it works!
