Yes, there's a config option kde settings (Desktop effects/Advanced).
You should set the compositign type to "Xrender" and the Qt graphics
system to native. Sometimes KDE does not accept changing the values or
changes them back at next start. In that case you have to set them
manually in the config file (without kde running):

/.kde/share/config/kwinrc in dection [Compositing] add/adapt to Backend=XRender.

What? I had the impression that this bug is long gone! What
emacs/distribution and what NX version are you using where this error
shows up?

I have done it successfully ~1 year ago using this document:
