Below is my code, a simple modal with element-ui on it.

  m-modal(:show="modal" @close="modal = false" centered)
  m-modal-body
    el-table(:data='queriedData' row-key="id")
      el-table-column(label="Node name" prop='iess' min-width="260")

When the modal shows, it seems struggles and tries two times bounces for putting itselft on the screen. I can see the background flashes two times when popping up the modal.

Any one has the similar problem or what should I do to avoid the "flash" ? Thank you.
