Update: using OpenGL 2 seems to have cured the glitching I have been 
experiencing, apart from the occasional lack of immediate updating of a region 
(like just now when I opened the KWin prefs dialog via the titlebar context 
menu, which remained partly visible).

I guess shouldn't be surprised that an older OpenGL standard is less problematic 
on my hardware, and wonder why I never thought of trying that before. Will have 
to do for now, thanks for the feedback.
