See screenshot...https://screencast.com/t/ehLHK8TX4FWhen exporting this particular file, a bunch of mysterious canvas space is being added.
Can confirm this bug has been in Photoshop for as long as the new export feature has been implemented, and they phased out "save for web". Have you noticed that export sometimes won't let you export at the size you want? you have, say, a 600x400 image, cropped to 600x400, and you go to export it...and what's this, Photoshop? You have to export to 599x400? Um, well, ok. And then you export and load it up on whatever project to find you now have extra pixels. That product image that you thought was on a pure white background? Yeah, now there's an ugly black line. You look like a f***ing crap photographer who can't even edit shots. Thanks Adobe. Glad your team is hard at work providing digital marketing reports, because that's what I really want from you, not software that works. So why does this happen? My best guess is the algorithm isn't using floating point precision in its calculations. Maybe whoever coded it used Int or Float for the numerical calculations. Who knows. All I know for sure is that 80% of my photos that look fine on export secretly have a 1px line extra pixels that SHOULD HAVE BEEN CROPPED TO MY CANVAS. No, I shouldn't have to delete cropped pixels in an effort to trick the exporter. Sometimes I have data I need to save outside of the canvas, I don't want to have to delete. Save for web admittedly doesn't have the nice compression that the export does, but it WILL let you export at the right dimensions and it WON'T add more pixels. The exporter should do what it says on the tin.
If you add a pixel to the image dimensions in the "export as" window it covers the bar up. Not ideal, but it seems to work.
Fixed in Photoshop 20.0 or later.
