The workaround for me is to always resize by clicking Alt, right click, and drag. At the end of the day, that's probably just straight up easier, since you never need to bother getting close to the borders of the windows.

I recommend changing the key to Super. As holding down Alt and clicking/dragging is often used by many applications and simply won't work then.

I just learned that you can use Super + Left Mouse to drag windows around and Super + Right Mouse to resize, due to this discussion. I have been using XFCE forever, mostly using hotkeys for tilling, and just did not know :D

Thanks !

Yes, it is best to use Meta/Windows key for system related actions (copy/paste, screenshot, application start, various windowing actions), and let Ctrl and Alt be used by the applications.
