Expected Behavior

Obs doesnt close.

Current Behavior

The dialog causes gnome to issue a fatal wayland protocol exception and closes the connection. This doesnt appear to cause a fatal error on other compositors (sway) but the window behaves weirdly suggesting something is definitely incorrect.

Replicated from a report in discord.

Steps to Reproduce

1. Launch obs
2. Link with youtube
3. Select "Manage Broadcast"
4. Select "Select Existing Broadcasts"
5. obs closes immediately.

Anything else we should know?

I doubt this is useful for us but the wayland debug log right before the crash.

Invalid surface size seems about right as we see the window size changing unexpectedly on other compositors which maybe is them accommodating this incorrect behavior. Likely the qt ui for this needs to be modified.

I have the same issue with OBS Studio 27.2.4 on Fedora 35.
OBS Studio logs: The Wayland connection experienced a fatal error: Protocol error.
The only workaround I've found is switching to X11 from Wayland.

I don't seem to encounter this crash on Ubuntu 22.04 running GNOME 42.0 or Ubuntu 21.04 running GNOME 3.38.5.

Edit: I'd missed the part about needing to select "Select Existing Broadcasts". This part is key, as the dialog otherwise will launch fine. It seems that the dialog might be resizing itself when clicking that tab. Maybe the new size it tries to become is larger than the specified maximum? It seems that the minimum size required for that tab might be larger than the specified maximum size for the dialog due to the QPushButton elements at the bottom.
