Your work-flow is a bit strange but anything you paste into the decomposed alpha = various degrees of opacity The alpha channel is a mask where Black = transparent, White = opaque, Anything in between = degrees of semi-transparent.
Some image viewers will show transparency (usually as a checker pattern) but some do not.
You can get the same effect if you add a layer mask (white) Layer > Mask > Add layer mask to the first image and paste the second image into that.
Want to lose the pattern ? Get rid of the alpha channel Layer > Transparency > Remove Alpha Channel .
Need the alpha channel but not the pattern, It can be set to white in Edit > Preferences > Interface > Display then the Transparency Check style drop down menu
My workflow might be strange because today is the first day that I have used Gimp and the workflow came about through trial and error. What I am trying to do is as follows:
I have an image and I have a roughness mask as a seperate image. So I want to add an alpha channel to the image so that I can paste the roughness mask into the image. Then when I load this into a game engine it only needs to read from one image instead of two. I tried Googling this but the answers I found either made no sense or they did not work.
