Background color artifact
I have this weird thing going on with my background color. I have drawn a background with the rectangel tool and added the color ##F1F0ED. Opacity level is 100% both in color and layer. Blend mode is Normal. The artboards in my design all have the color #FFFFFF, in other words they are all white. When viewed in design specs my whole background looks like this. See attached sample. It looks like a pattern of some sort but it has NOTHING to do with my background color, it gets even weirder when it appears correct on one machine but not another. Both machines are running latest W10 Pro. I even sendt the link to other people outside my LAN and they also got this pattern result instead of the actual color. When I view the shared prototype and spec file on my 4K laptop I get this artifact result but when I view it on my 2560 x 1440 monitor it looks correct. I have no idea if that has anything to do with the result but that's how it is. What's happening? It's exported for web and for development. There's so much instabilities with all the CC services like desktop prototype viewing, code specs etc. Is this a bug?
