Trouble making a Scroll View in a 3d Panel

I am not sure how to fix your issues but this popping in and out of view problem happened to me when I had a shader or image that didn't have alpha support. Fixed it once I had changed the shader and material settings. Might be worth a look.

Does the shader in the Refractive Atlas prefab have alpha support?

I have no way to check on your system. But if you go into the colour properties and move the alpha slider back and forth, if you get strange results you can assume it is shader related.
When I had an incorrect shader selected moving the alpha alpha did nothing until I set it to 0, then I saw nothing.
