Symptoms

Unable to launch the game. Getting the error:

"The game can not continue: Please change your display settings to be 'High Color (16 bit)'"

Reproduction

Simply launch the game and choose "Play Creatures Docking Station"

Notes

There simply no easy way to set 16bit color depth in Linux.

Wine suggest we have to fiddle with /etc/X11/xorg.conf.d/ or /etc/X11/xorg.conf and set something along the lines of DefaultDepth 16. But that will cause Steam not to start. See https://wiki.winehq.org/FAQ

10.4 Graphics
10.4.1 My application complains about being unable to change the resolution or color depth
You generally need to edit the Screen section of your /etc/X11/xorg.conf to support additional color depths and resolutions. There may also be a problem with Xrandr.

Another method is to use Xephyr. See https://wiki.winehq.org/256_Color_Mode
So far adding this line to Launch Options works for me:

Xephyr :2 -ac -resizeable -screen 1280x720x16 & env DISPLAY=:2 %command%

Additionally need to add these registries to steamapps/compatdata/1659050/pfx/user.reg or use protontricks
to disable window decoration and window manager control
since there is no window manager running in Xephyr.
Running mutter or another WM in Xephyr seems to mess things up for me.

Going full screen and then back to windowed screen seems to break the game however. Audio still running though. Alt+Enter sometimes fixes the problem.
