Videos unplayable on Poco F1, no fix regardless of Bug report

Hey I have a problem with my Phone when playing videos (doesnt matter if Browser or file Explorer).
Its without sound and waaay to slow. Extremely jerky.
I found out that it has to do something with the audio. Because when i am connected to a speaker via Bluetooth it works fine.

I looked on the Gitlab forum and it was reported several time, almost a year ago.

Is there hope for this issue? Do i have to wait for the next update?
Do i just post another bug report?

And i tried to create a /e/ account and the Email never arrived (Yes, i looked in the spam folder)
Is there a support i can contact for this issue?

Thanks very much!
