WebIDE: carousel blank page

Hello everyone,

today's problem is an interesting one.

We have a UI5 app for IOT demo purposes, which has all other controls embedded into a carousel. The app, however, only works on very few computers, while on most computers the carousel is not displayed and the respective area is simply blank. This seems to depend on some user-specific local file or setting, since different users on the same computer have different outcomes and users for whom it works fine, do have the issue on a different computer. We compared browser settings and runtimes but did not find any clue whatsoever.

If anyone can help with this puzzle I will gladly post the code snippets you need.

Kind regards,

Konstantin
