Small window/another duplicate of brave keeps on popping after watching some videos either on youtube or playing games


Description of the issue:
I don’t know why, but every time I watch a video or something or play any game while Brave is open, it creates another duplicate of the browser with the same tabs, etc., but it doesn’t use any extra memory or anything. But then when I close the window, the closed one becomes like a compressed window, and it won’t go until I restart or create another desktop, and reinstallation doesn’t work. (It doesn’t create another separate brave but shows while pressing ALT+Tab)
How can this issue be reproduced?

  1. Watching videos on youtube
  2. Playing games while brave is open
