Width of "grab-zone" for window edges/corners is too small (1 pixel)

[ericmarceau-rogers]

Expected Behavior

When I do a mouse-over near a window's edges/corners, the edge detection band width should be more like 5 or 7 pixels wide, in order to reduce the wrist tension/stress of mouse positioning in order to be able to grab those for window resizing.

Actual Behavior

When trying to grab window edges for resizing, the "grab-zone" appears to be only 1 pixel wide, which is MUCH too narrow. I spend about 10 seconds every time trying to correctly place my mouse to grab an edge/corner for window resizing.

Steps to Reproduce the Problem

1. UbuntuMATE 22.04 LTS
2. Set Window-border theme to "Yaru-dark"
3. Set Window controls theme to "Yaru-bark-dark"
4. Open a MATE terminal, and attempt to position cursor near edges for resize
5. Open a Gvim terminal, and attempt to position cursor near edges for resize

Upstream check

"gsettings" don't seem to have any effect.

Manual set of Adwaita for Control theme.
Adwaita not available for selection as Window theme.

I've included a snapshot of the installed libraries, which seems to suggest that the Adwaita Window theme should be there, but it is not:

Other possibly relevant info

I originally posted my issue on the UbuntuMATE site, but feel it may be more relevant here. :-)

Your issue seems to be that you're using Marco without compositor. This means that the invisible borders (which can only be drawn by a compositor) are not present. This is not a theme issue, nor a window manager issue. This is a limitation of the rendering engine.

Enable the compositor to fix this issue. Alternatively, use keyboard-mouse combination for easier resizing (hold Alt while right-clicking anywhere near the inside edge of a window to resize)
