If you want the video to work, you will need the proton-GE.
Videos are broken
Made left trackpad vertical scroll
All videos were broken, some graphics did not appear
Since videos are broken, you can't experience all the content
Videos, some backgrounds and sounds do not play
Videos do not play, so the main menu has color test bars in the background, some backgrounds do not show up which causes the text to smear around and makes it unreadable and some sounds don't play at all. This being a digital magazine article these things being broken kind of makes the whole thing unusable.
If you're okay with some weirdness on transitions and a few of the least important videos, you can still enjoy the content here.
Loud beeps on software startup and at the end of videos.
Some chapter transitions wouldn't work, and 3 videos didn't play or had issues playing.

Proton-5.9-GE-4-ST GloriousEggroll
"Beep" noise at the end of videos
Unplayable with Intel HD4000 GPUs because of graphical glitches. Probably works with something newer.
Proton-5.9-GE-3-ST GloriousEggroll
I tried using the GloriousEggroll proton fork as others suggested, which fixed the black screen at startup
There's a loud buzz in the intro
Many elements flicker, including images, which is game breaking for a documentary
Using Proton 5.0-9 gets you a black screen. Using Proton-5.9-GE-3-ST fixes the problem however in my case I now get an error message. This is probably due to incomplete Vulkan support on Intel HD4000 and newer architectures will probably work fine. This is unfortunate because this game works fine with older, less powerful computers on windows. Using WineD3D allows me to launch the game but the main menu is black with only play and exit displayed, and in-game, many elements flicker, including images, which is a dealbreaker.
Proton-5.9-GE-3-ST
The intro has a loud noise for about half a second at the end.
occasionally hangs seemingly at random
Nevermind menus, part of the presentation relies on videos, which don't work.
No video playback
Touchsceen not supported
Due to unsupported video, you get stuck with a black screen if you don't skip
While there are minor bugs, the bulk of the content in the book works as intended.
Occasionally when audio stops playing (e.g. a video ends), a loud harsh buzzing sound will play briefly
The backgrounds for some chapters fail to render properly. This does not affect readability.
Proton-5.11-GE-3-MF GloriousEggroll
5.11-GE-3-MF GloriousEggroll
Proton 5.11-GE-3-MF was required for videos to work https://github.com/GloriousEggroll/proton-ge-custom/releases
A singular crackle sound is heard when any video finishes.
A few chapter titles aren't rendering correctly, but the chapters themselves are perfectly readable, Some videos (thankfully of minor importance) are skewed to one side
