Yes

I presume you see this with the Linux version?
Thanks. I found that the saves from July 4th didn't show this small screen. I also checked v021 through options and a new game. The first had the problem, the second not. But now I see that loading v020 -- the start of the Gabriella episode -- doesn't have it yet and also sampled five earlier episodes in each route. None have it. Tonight I will try to confirm your finding. It helps when we can pinpoint it occurs...
Well at the moment three people have this bug. The second reporter didn't answer my questions yet, so I don't know which OS he/she is using. It could be a bug in the Linux player. Although Visionaire makes updates to it, I have the impression that it isn't well maintained. For example linking to a very old libpng12 is strange. Especially because the provide some libraries in the lib64 and not this one. If you need that specific library they should include it.
However I also had the impression that code in the game triggers it, because not all saves had the problem. And it seems you confirmed this. So it is probably some innocent code from Nenad which triggers a bug in the Linux player. That is what the limited data at the moment suggests. If someone report this in macOS or Windows then this hypothesis is false, but that is what good bug hunting entails...
No, not yet. Also the Visionaire developers seem very stubborn and think that their code is error free. I don't like that attitude
BTW which distribution are you using? And what is your graphics card?
i Don't think this is libpng related.
however here is my info:
# game
ver: 022
played from scratch, no old saves
# libpng
