resizing container doesn´t redraws

Hi
in my App i have a container with many elements.
If i resize the Browser window, the main container is resizing (OK).
But if i enable Chromes Dev Tools, embedded in main Window, and hide it, the panel doesn´t resizes und a blank part appears, where the place of the dev tools was.

Hello @ChristianNRW ,

Unfortunately, it’s difficult to recommend something. On our side, there is no such problem. Could you please send us a snippet with a code where I can check the problem? And, it will be useful to know, which browser(+version) and OS do you use?
