Created attachment 111601 [details] Screenshot showing the copy/paste issue. I have this issue when ever I try to copy something from Krita and paste it to other paint programs for Windows, like Paint Tool Sai or Clip Studio Paint, it offsets and cuts a part of my picture off. Have no issue when copy and pasting within Krita itself. I'm using Windows 7 SP1 64-bit.
Does it also happen with mspaint? (Asking because that's a bit more trivial to test with :p ) For the record, I cannot reproduce this on KDE Neon(Ubuntu 16.04) when copying to Gimp, so it is not a platform agnostic issue.
Does it still have that offset at 100%. In your screenshot you have Krita set to 100% zoom, while in SAI you have your zoom set to 75%, which can create display problems. I am not sure if that is the reason, but your display can look weird sometimes if you are not at 100% zoom. It would be good to test it in other programs as well to make sure it isn't a problem with SAI.
I cannot reproduce this issue. How do you exactly select the circle?
Created attachment 111709 [details] Pasting to Photoshop shows up a solid square or rectangle, no matter what selection tool you've used. Okay, so I did some more experimenting. First off, in case you did or didn't know, the circle is on a transparent background instead of a white background. Now besides Paint Tool Sai and Clip Studio Paint, I tried Photoshop CC 2014 and MSPaint and it's showing no transparency at all; just one color (see attachment). Tried all selection tools, still the same results. Tried recreating the circle on a different layer and copy, same results. Tried recreating the circle on a vector layer and copy, also same results. I also tried it on my laptop, which also runs Windows 7 64 (both the laptop and my PC run on the Home Premium version if you're wondering) and have never installed Krita before up until now. I also got the same results there, so I now know that doing a clean uninstall and reinstalling Krita won't do me any good.
Created attachment 111710 [details] Testing Paint.NET Pasted it on Paint.NET. While it pasted no problem, it pasted with a white background when it's supposed to be transparent. Also, copying and pasting at 100% zoom on all programs didn't fix the issue.
If you try to copy and paste a layer with transparency in it on Windows, the Windows clipboard may strip the alpha channel, depending on what version of the image the receiving application decides to accept. It's a well-known problem. See https://bugreports.qt.io/browse/QTBUG-11463 But that doesn't seem relevant for the problem you originally posted, where a sliver of the left-hand side of the clip is pasted on the right-hand side.
