Dashboard not displaying on iOS

Is there anyone aware of a display problem of the dashboard on iOS devices (iphone and ipad)?

My dashboard is correctly displayed on any Android browser, while on iOS the dashboard is all black and not responding. Tried with iOS 14.4.2 on iphone, ipad, Chrome and Safari.

EDIT: I have found that the problem is related to the node node-red-contrib-ui-artless-gauge: it blocks the whole dashboard display.

Same on my side. Isn‘t a new problem on safari OSX and iOS. But‘t i never found out what causes this. Some work some not. I have one tab with 6 gauges working and abother one where even one single causes a black screen.
