I want to do some captures like I did here on specific versions on W10. How is everyone obtaining specific versions and installing them?
Having updated my windows what i think was 1903 to 1909 (2004 isn't available to me yet), and repeated some capture tests I got different results. Specifically colour value r0,g0,b0,a0 (transparent black) when from not dithered, to heavily dithered. I am thinking that something might have changed with how windows handles the alpha channel (transparency).
My entirely uninformed opinion on why windows updates are affecting people is that there are subtle changes being made to how windows handles colours. And this in turn is affecting what a gpu driver will dither, and the frequency (ie every frame, every 10 frames etc). And lastly, the user groups primarily affected seem to be those with laptops, which may have dithering forced on in some manner to improve colour representation on their internal panels.
