This is now my 4th Theme and the problem is the same on all themes.
 
How to remove transparency OR a theme conversion problem, BUG?
You can see my loop graphic and how it turns faded on when saved in the Theme editor.
It’s not a huge issue as you can see but on the loop button you can see that all but the blue buttons are distorted. I have tried many tricks put I can’t fix it. also the lock came in fine...
 

Which image editor are you using?

Photoshop.

Please would you export your edited loop button image from Theme Editor, and then send it to us (a PM would be fine)? It's worth checking that the image dimensions are exactly 170 * 34 pixels too.

Dave000 - I can't help any, but by the looks of what you've posted I'm really going to like your theme work.

Are you absolutely positive you are saving the edited image as a PNG with alpha (transparency) channel?  I use a different image editer (Xara designer Pro X) so I cannot comment how to confirm this in Photoshop.  I initially had this issue with some PNG images and I found that I was inadvertently saving the PNG files without alpha channel causing the white border effect as shown in your example.  I Re-saved the same PNG files with an alpha channel and the white frame disappeared.

Thanks!
I keep deleting the FTH files to try and keep things net. Right now I am working with CW to fine out what's going on... Too little time right now but I'm thinking that it could be a win10 thing. when I have time I will install it on win 8 system and try it... later today. I hope.
 
Peace!

I have tried many tricks to get passed this, now working with CW... Thanks just the same :)

I found a work around using an old Corel photo package yet still with
other issues. :) Still have a lot to do....
