Since I have a new monitor 34" Samsung (S34E790C ) desktop icons are "auto arranged" when PC is awakened in sleep mode. First I did not notice it as sleep was not activated. But since sleep is activated it happens. Not after rebooting.

graphics card is GTX 1080 with newest Nvidia driver, cable is display port cable 1.2

What can I do to solve it? It is a real PIA with such a widescreen

did google search but same problem was described with two monitors
