In my case, at least in construct 1, I was having some trouble with transparent areas.
While in photoshop it was showing everything ok, as soon as I exported the images and put them on construct, some little pesky white pixels appeared randomly around the image, sometimes 1 or 2, other times like 20 or so =O
that's some exporting bug that was happening to me, not all the time though, I've got pretty good transparencys with lots of sprites
Anyway Ashley, thanks for ur feedback, it really feels nice to know those things are coming next patch =O
And I'm not saying it wasnt a big deal, just making sure I wasnt the only one with this strange feeling, I just had to let it all go and share those feelings ya know
but thanks again all construct 2 dev team. =)
Edit: corrected some grammar, sorry about my weird english i'm not a native =/
