I believe the parent is referring to how GNOME 3.0 had some really bad resizing grabs. Single-pixel widths at the edges, and almost impossible to hit corners.

Latter versions significantly improved it.

Has been a major issue for me with Xfce and Gnome over the years, mostly just switched window managers.

		Xfce is just ridiculous, it has 1px thin area to grab, and last time I checked they just mentioned you should use alt right click instead.
