This is likely a problem that will never be fixed, it is pretty much how the web works.
@roband7 As for resource versioning, it actually does for the resources that matter. The css and js files are versioned by their hash. The images files, with the exception of the files that are used for theme design, are served from a different url on update. Those two things should help with any cache issues. The only other thing I can recommend is to always change the resource url on update of a slider or theme image.
