Please describe your issue in as much detail as possible:

When I use it in portable mode, every 2 or 3 restarts, changes from Gaming Mode to Desktop Mode, suspension; Plays the intro video by default 2 times. If you have an external monitor or television that does not happen, it works without problems. I have had this error since the last beta update.

Steps for reproducing this issue:

1. Turn on the Steam deck. (Sometimes the intro fails because I turned the Steam Deck on and off several times.)
2. Switch from Gaming Mode to Desktop Mode several times.
3. The video plays 2 times of the steam logo by default.
