Plasma 5 no transparency [SOLVED]

Last week's pacman -Syu killed my plasma 5 transparency.
In the forums I do not see any posts complaining of a similar problem, so I must assume is an isolated problem.

I did not have much time until now to begin looking for a reason for this problem but this is what I just found:

KCrash: Application 'kwin_x11' crashing...
Application::crashHandler() called with signal 11; recent crashes: 2
KCrash: Application 'kwin_x11' crashing...
KCrash: Attempting to start /usr/lib/drkonqi from kdeinit
Warning: connect() failed: : Connection refused
KCrash: Attempting to start /usr/lib/drkonqi directly
/usr/bin/kwin_x11: FATAL ERROR while trying to open display :0

It seems kwin_x11 is receiving complaints... I, however, would suspect that if kwin was failing I would have more troubles
that I do ... so, I'm not sure I trust it to be the source of my problems.

In fact **everything** is OK, except for the transparency problem.

My system specs are :

OpenGL vendor string:                   NVIDIA Corporation
OpenGL renderer string:                 Quadro K600/PCIe/SSE2
OpenGL version string:                  3.1.0 NVIDIA 370.23
OpenGL shading language version string: 1.40 NVIDIA via Cg compiler
Driver:                                 NVIDIA
Driver version:                         370.23
GPU class:                              Unknown
OpenGL version:                         3.1
GLSL version:                           1.40
X server version:                       1.18.4
Linux kernel version:                   4.7.2

If anyone has any ideas to troubleshoot the issue please post.

Thanks,

R.

UPDATE:

I switched in Display and Monitor -->Compositor the Rendering backend = XRender and that was it.
I had been using forever OpenGL 2.0 without problems ... but that took care of the problem. Go figure.
