My answer may confuse you. I'm not sure which novel application you're referring to, nor do I know what problem you're facing. However, according to my understanding of the online literature industry, if you encounter abnormal situations such as text flickering or stars when using a novel application, it may be caused by the application itself. In this case, it is recommended that you try to restart the application or uninstall and re-install it or try to use it on other devices. If the problem still exists, you are advised to contact the customer service department of the application and report your problem to them so that they can further investigate and fix it. As for whether the MC product manager is blind or not, I don't know and can't comment on this.
