Proton is not supported in this bug tracker
Proton issue has been closed.
Running steam with unlockh264 fixes the video bug without the need of proton-ge which seems to auto enable the features: steam steam://unlockh264/
The GOG version is also fixed by loading it with steam as a Non-Steam game.
I'm not aware of a GOG command to enable the equivalent dependencies to fix the videos.
The specifics that fix the video still need to be determined.
If winetricks is required to fulfill missing components within wine then this issue should be left open until wine fulfills whatever is missing.
Otherwise if it's just missing dependency issues like gstreamer then this issue may be considered closed.
