I'm experiencing the same issue, in both windowed and full-screen modes. Furthermore, the pointer doesn't stay centered when you pause the game, and when you try to click, if the pointer is outside the game area, the game pauses. It also moves to different positions depending on camera movement, which doesn't happen in the Java version or previous Bedrock versions.
