HI toyotadesigner, thank you for the answer!
It happens with all kind of images: cropped, not cropped, pngs, jpegs.
The only problem is that sometimes it happens and sometimes no.
The image is perfect and has no frame.
It's like 3 days I'm trying to replicate the error but I failed. For now it seems all is working fine but our customers and our colleagues tell me they are facing the problem. (I'm using same files and images they are trying to print and for me it's always working fine).
I thought it could be a visual glitch but when you print the frame gets printed and that's so annoying.
I will attach a ".sla" file and the PNG used that seem to be broken for some people and you will clearly see there is no problem in it. (unless you face the error).
