So, to further add to this, I have fully uninstalled GIMP and GWS, including all library associated files, rebooted etc and then reinstalled both apps as new.
Issue still persists. Some images load ok, and I now suspect anything with either a gradient or a fade is causing this issue.
Not ideal for a basic image to not work like this.
Have raised the issue with Samsung Developers directly, however, not convinced they will be able to help. Personally I think GWS is bugged…
The image you have attached works just fine at my end. See the result. I can’t understand why it doesn’t work on your system. You may try renaming it and make sure the format should be PNG.
I’ve been in touch with Samsung Developers now also and they confirm my file works ok on their system, so some more files sent to them so see what they come back with.
