Hi @CrisjovanoGumaraes,
If the issue is not occurring in the current release version from app store, it is likely the issue is related to the AppStudio version and Survey123 template version you are using.
When a Qt canvas is used in the app, we have to scale images based on the scale factor and device pixel ratio of the device/screen being used. There are many areas of the code and fixes/patches from Qt that resolve issues around only 1/4 image being displayed, which is a scale factor problem.
If you can confirm the exact version of AppStudio and which template version you have, that will help?
It may be worth waiting until the next 3.14 update of the template is available, as that will include fixes that the previous template may not.
Regards,
Phil.
