I had seen something similar, but hadn't traced the problem as finely as 
you have.  I have my borders set really small so didn't notice that bit, 
but I *DID* notice that I was sometimes unable to grab an edge of the 
window if it were too close to the edge of the monitor (I have a multi-
monitor setup and noticed it on the between monitor borders too) and 
resize, when I had been able to do so before.  And that was frustrating.

But I'm actually running kde-4.11-live-branch and after reading this post 
I realized I hadn't seen the problem after the last update, and couldn't 
reproduce it on demand ATM either, tho I can't say for /sure/ that it's 
fixed because as I said I hadn't resolved the problem to the extent that 
you have, but anyway, with a bit of luck it's now fixed and 4.11.3 
release (tagging due on Oct. 31 and release on Nov 5, according to the 
schedule on kde techbase) should have the fix when it comes out. 


Meanwhile, the resize workaround I had been using was to use the mouse-
drag+keyboard-modkey combination.  

See window manager settings (available from the window menu of any 
window), actions, window actions, inner window, titlebar and frame 
section.  The default mod-key is IIRC alt, but I changed it to meta (aka 
the windows key, which I use in various combinations to activate various 
window actions, windows key, windows actions so it's easy to remember) 
here.  And the default modkey-left-button-drag action is move, modkey-
right-button-drag is resize.

So I hit modkey-right-button, clicking to drag in the window but with the 
modkey active so it activates the associated window action instead, and 
drag to resize with that modkey-right-click anywhere in the window, not 
just on the edges.  That way I don't have to grab the (small) border, and 
can instead just modkey-right-click in the general area to get the resize 
arrow, and it's much easier since that effectively makes the whole window 
a giant resize button, kind of like targeting the broad side of the barn, 
it's hard to miss! =:^)
