I've figured out the problem; it's because of the selection quality. You can set it to 'Pixelated' to stop it from going funky: I would like to note that even with this fix, the selection goes from being 4x3 to being 4x4 pixels after rotation; I'm not sure why and I don't think it's really an issue, but I thought I'd bring it up and attach an image of it nonetheless. Thank you all!

Thanks!

I'm not entirely sure what you're referring to when you say I must, "center [my] image first," but I will note that the selection box does not appear misaligned prior to rotation. Apart from that, I am selecting it before rotating, and yes, I am using the latest version of paint.net. Sorry for the late reply; I expected to get email notifications if I check the 'follow topic' checkbox, but this seems not to be the case.

I can indeed confirm that I am using shift to lock the rotation; the problem still occurs on my end. Having tried it again just now, the selection box itself is sometimes misaligned as well, but not always. I am attaching another screenshot.

This bug still seems to be in effect today, albeit not quite as bad as before. I'm attaching a new illustration of the current behaviour today. I may be wrong about this, but I think this was at one point no longer a problem, then started happening again after some update. Any hope of it getting fixed?
