5.4.0 interface freezes with default Flatpak permissions

When running 5.4.0 flatpak on Fedora 43 with default permissions (of which the relevant part is: socket=X11 enabled, socket=wayland disabled). I have an AMD Ryzen TR 7970x CPU and an RTX 5090 GPU.

Darktable starts, but is unusable. The interface completely freezes upon the first image operation, often right after rendering the thumbnails.
The description of the symptoms appears to match this:

...however it is not clear if it is exactly the same issue. The issue also happens with 5.2.1 Fedora-native rpm.

Things that do not fix the freeze: 1. Disabling OpenCL or specific drivers, 2. Disabling MIDI device enumeration.

I have found a workaround that fixes the issue:

1. Open Flatseal,
2. In the Socket section, disable socket=x11, and enable socket=wayland
