When opening Battlegrounds, sometimes a mini-game or special event image overlaps the screen before clicking the Play button. It shouldn’t be there and makes the UI look broken or confusing.

Steps to Reproduce:

  1. Open Hearthstone.
  2. Go to the Battlegrounds mode.
  3. Notice an overlapping image on the screen before pressing “Play.”

Expected:
Only Battlegrounds UI should be visible — no leftover images from other modes.
