I've been having this issue in Manjaro 0.8.10 / KDE 4.14.0 where none of the windows are resizable by their edges. Can still resize through right-clicking the title bar -> more actions -> resize, but not by grabbing the edge of a window.

Replaced my .kde to .kde-old and figured out that the files responsible for this behaviour are ~/.kde4/share/config/auroraerc and ~/.kde4-old/share/config/kwinrc

Neither of them exhibits the behaviour in isolation, they both have to be present in order for the resizing to fail.

Not too sure why this is happening... I'm pretty keen to resolve the issue directly, rather than simply excluding the files from my setup.

Here is the contents of ~/.kde4/share/config/auroraerc

Can anyone identify a parameter (or two) that I can change to correct this error?

Many thanks in advance...

I cannot directly answer your question but you can resize windows by pressing Alt, then right-click dragging the window. That's much more comfortable than the fiddling with the borders anyways.

Maybe this helps

what's the output of
xdpyinfo | grep -i xinputextension

does it work with borderless oxygen decoration?

@scummos : unfortunately that method of resizing windows is also not available to me.
@luebking : yes, it does work with borderless oxygen decoration

$ xdpyinfo | grep -i xinputextension
XInputExtension

Many thanks for your help resolving this...

Looked up the code. An aurorae theme that wants to support this, needs to add an "extendedBorders" element.

The "Air-black-remix-green" svg does not seem to contain this (thus invisible resize borders are not supported) - but I've little experience with Aurorae theming.

Bordersize=0 seems to be the problem on auroraerc, kde can't seem to resize tiny windows for air-black themes; setting it to regular will let you resize windows again.
Set BorderSize=1
