during fast scroll white flicker or flashing in Sumatra pdf with default MainWindowBackground color

[prashantk100]

sumatra pdf has default in advanced settings , MainWindowBackground = #80fff200
but this causes white color flicker or flashing on fast scrolling in pdf
in fit to width page settings ( zoom zround 200%)

To Eliminate white flicker or flashing I have changed Sumatra pdf Main WindowBackground color to black and its working
MainWindowBackground = #000000

and also added GradientColors in section FixedPageUI [
GradientColors = #000000

I request to detect high contrast mode on windows and change default to
MainWindowBackground = #000000
in advanced settings in Sumatra pdf reader to eliminate white flicker under dark theme or high contrast
or at least document the solution.

regards
Prashant
