Furthermore I have tested the KDE effects in 14.04.x (KDE 4.13.3);

When I disable the following KDE effects, the memory leak is not occurring.

Cover-Switch (in german: 3D-Fenstergalerie) and Flip Switch (3D-Fensterstapel)

This is the result of testing for one week.
The memory usage of the graphics card (nvidia-smi) stays normal and the kwin process usage grows to ~ 100 MiB RAM (2K:2560x1440) and also frees memory back, if windows are closed. Xorg process at ~ 100 MiB.

I will test this further, but I think this two effects were the culprits.

This problem is only with the nvidia binary driver (tested until 352.09), it is not with the driver nouveau, intel, radeon (fglrx not tested).
