The container that has the background is collapsed by default if you’re viewing your own profile. If you click on expand here
you’ll see the background.
It’s collapsed by default if you’re viewing your own profile because you usually care more about the information below the image rather than the image itself - especially on mobile.
If you’d like to override this behavior, you can add something like this in your theme’s common > header
tab.
<script type="text/discourse-plugin" version="0.8">
const discourseComputed = require("discourse-common/utils/decorators").default;
api.modifyClass("controller:user", {
@discourseComputed
viewingSelf() {
return false;
}
});
</script>
