...:sigh:...
First of all, does it work with vanilla wine ?
No, it doesn't. The same.
Second, does it work with staging, but without dxvk ?
Nope, it also doesn't.
Third, does it work if you remove vaapi gstreamer plugins ? - OK, this one might be a red herring, but as I don't use dxvk, I can't tell whether or not are those 'glx: failed to create dri3 screen' expected or not and if they have any impact on the gstreamer failures (which - surprisingly enough - don't seem to come (as it's usually the case) from *missing* plugins).
If I knew how to remove them (or if I even have them), I'd do it just check.
Oh, if those animations are accessible outside of the game, run something like ffprobe/gst-discoverer-1.0 on them and post the info.
It's a Unity game with its classic file layout, so no. It's not possible.
