X comes with its own blockchain.

I've experienced the same thing, especially after many hours staring into a monitor. My guess it may be a neurological thing of the eyes/brain adjusting to the ever changing pixel flickering through out the day, similar to after-images and retinal fatigue.

Thinking about this issue from another direction. You mentioned he had an issue with chronic fatigue. What if that is actually the main factor for him not being able to focus on work. The psychological factor of not being able to deliver on promises especially since you are family could drive him down a spiral even more. Feeling bad for playing games, then playing even more games out of frustration, because it kills thinking time. I met countless people with similar issues over the years and many of them could resolve their problems changing their habits and diet to a healthier one, making sure they get all the necessary vitamins (especially B12,D if they happen to be vegetarian/vegan), and of course doing physical excercise. Just doing low sets of simple Push-ups, Squats, short running, ... 5 days a week can help tremendously in the first few weeks with mental stability.

If the fatigue is not his problem, it could be he is just not believing in the success of your mission/product anymore and feels bad about, does not know how to approach you about it.

If he is still believing. Try to attack the health issue, motivation first.

You should definitly have a serious talk with him what you both can do to improve the situation.

Warning: This is scam!

First of all: One of the most awesome use of autostereogram i have ever seen! I always wondered if that was possible. Thank you!

Question, did you experiment how to reduce the flickering? Or use of colors?

I am asking since twitch announced that it might be forced to "shutdown" its service in the European Union due to the new copyright reform(article 13) which most likely passes later this month.[1]

Maybe ask that question over at teamblind? According to a somewhat recent discussion of Sep 2018 at teamblind the TC (total compensation in one year, usually not counting any perks) should be at least $750k+ TC, source: www.teamblind.com/article/Engineering-director-at-Google-uaJEgaho

Another reference might be: www.levels.fyi/SE/Google/Facebook/Microsoft

Levels does not have L8 estimates yet, but L7 is already beyond $600k+ TC.
