Greeting from Syncfusion. We have validated you query, we need some clarification from our side for this issue.
Query 1: Can please tell us know which version you are using in SfTabView.
Query 2: Are you facing the control overlap issue for all view or especially when using video.
Since we are not aware of your exact application scenario, so we request if possible, provide sample based on your application along with replication procedure or share a video link to replicate this issue. This will be helpful for us to investigate further and provide you a better solution at the earliest.
