I have encountered a problem with zooming using Ctrl+mousewheel. When I zoom e.g. from 89% to 100% (as shown in toolbar), the image itself is stretched a little - some pixels looks fuzzy and this represantation is unusable for direct pixel manipulation because the user can not rely on what he sees.
I think the problem is caused by some internally keeped zoom value (e.g. 100.0023%) but as a user I want to be sure that for 100% and multiplicities I can see the whole pixel. Otherwise I cannot use Paint.NET for pixel manipulation which is pity.
See this screenshot:
Thanks for the answer if this is considered as a bug and will be fixed in new versions.
