Ошибка UI: заголовок дублируется после входа в бета9 dev

[levonyan021 (Erik Levonyan)]

After updating to beta9 dev, only the header is displayed after authorization. When clicking any button, the header gets duplicated.

Does it also happen in safe mode?

Is this now fixed, was it a custom component?
