Description Filippo Landi 2021-03-26 13:36:08 UTC
Description of problem:
Fedora 34 beta clean install, updated and using default settings.
On Wayland (default setting) the system freeze when selecting the "move" option on a picture in picture video (I have tested it with YouTube videos).
It doesn't happen with Xorg where it will move the window just fine.

Additional info:
I have an Nvidia GTX1060 6GB using Nouveau driver as it is the default.

Can you please a screencast of it?

Screencast of what happens

The moment that the screencast stops is when I click "muovi" (italian for "move") and I see a black screen (video driver crashing?). 
However now the black screen doesn't show glitches and I have noticed that after a few seconds (I would say 5 seconds) it recovers but at the login screen, instead this afternoon I had glitches with the blackscreen and the PC seemed unrecoverable so I had to force shutdown.  
Maybe something has changed since I have used Xorg after I have experienced the bug and now I just switched to Wayland for doing the screencast.
I can make a video with my phone in case.

I see, Thanks. It works for me on Fedora 33 - can it be a Fedora 34 regression? (btw. you can move the PIP button with pressed left mouse button).

I updated my system to Fedora 34 but I can't reproduce it.
