Bug ID: 54684
           Summary: Sakura no Toki (SakuToki): thumbnails on save/load
                    screen are all-black
           Product: Wine
           Version: 8.3
          Hardware: x86-64
               URL: https://trial.getchu.com/D090/968350/sakuranotoki_tria
                    l.zip
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2

terminal output for 8.3 without/with DXVK

The given URL links to the free trial version / demo of the game; the full
version behaves identically.

Use unzip -I shift-jis -O shift-jis to extract the ZIP, to avoid garbling the
filenames.
Run サクラノ刻第I章体験版.exe; you'll probably want to set LANG=ja_JP.UTF-8.

1. Start game.
2. Wait until you get the regular UI [it's just a few seconds, but you can
press left-ctrl to speed it up a bit].
3. Save the game.
4. Note that the thumbnail doesn't show the screen you're on but is all-black.

If you examine the "savedata" directory, you'll notice that there's an
all-black PNG alongside the save file; in other words, it seems to be the
capture that fails.

Installing DXVK into the prefix "fixes" the issue.

That's why I chose the d3d component, by the way. I hope that was the right
thing to do; if not please accept my apologies and reassign.

Just FYI, 8.7 is still affected.
[Since Ubuntu 18.04 (bionic) isn't getting any official packages anymore, 8.6+
are built from source.]

For completeness' sake, I noticed that the thumbnails aren't always broken, and
there's a pattern to it.

This is an 18+ game with some graphically explicit scenes, and in those scenes
alone I consistently do get proper thumbnails. (It's not a game bug, on Windows
both kinds get thumbnails.)

It's worth noting, however,  that the method of generating them may be
different: In 18+ scenes the thumbnails have certain bits manually blurred,
i.e. the thumbnail for those may be hard-coded whereas the regular ones are
likely screencaps of some kind.
