But I can't see the screen of ios 11 device frequently
Environment(version of libraries, mac OS, iOS, etc)

It's seems that the ios-minicap is not very stable in iPhone 8+ ios 11 environment

Same problem here.
Opening http://localhost:9002 in the browser often shows a red box. Upon repeatedly starting up the minicap and the app.js, occasionally the screen shows. I am using an iPhone 8 Plus.
