One second black screen when changing pages , on this site.

Since the upgrade from 1809 to 1903 , Im having "one second " black screens when going from one page to another , on this site ( win-raid ).
Never seen this before , had this troubles on another site also , chanced my back-ground-image to default and the black screens are gone .
My question is ; how to get rid of the black screens on win-raid also !

Show a video screen capture of what you mean so someone might be able to advise.

Its just a black screen , between one page while going to the other selected page !
About one/two seconds black , then the other page opens…

Could be display driver issue on your end, or graphics card doesn’t have enough power to quickly display the background image for a second or two until it re-loads.
I’m not sure if there is black background behind the image or not, only plutomaniac or Fernando could answer that one.

unistall display driver and reboot. if it still show black screen then its hardware gpu issue. what power supply do you run?

win10 is a crap OS. roll back to win7 and most problems will be sorted…
