--- Comment #4 from Anastasius Focht <focht at gmx.net> ---
Hello folks,

confirming and adding one more .NET 4.7 WPF app 'Gaea 1.0.19' from bug 47282

https://web.archive.org/web/20190523115754/http://viridian.quadspinner.com/gaea/Gaea-1.0.19.exe?f=1

--- snip ---
$ pwd
/home/focht/.wine/drive_c/users/focht/Local Settings/Application
Data/QuadSpinner/Gaea

$ wine ./Gaea.exe
...
003b:fixme:d3dcompiler:make_assignment Check for casts in the lhs.
003b:err:d3dcompiler:compile_shader HLSL shader parsing failed.
...
003b:err:ntdll:vDbgPrintExWithPrefix 65: MIL FAILURE: Unexpected HRESULT
0x88760b59 in caller: intermediate rendering error
...
003b:err:ntdll:vDbgPrintExWithPrefix 65: MIL FAILURE: Unexpected HRESULT
0x88760b59 in caller: The render thread failed unexpectedly.
--- snip ---

'winetricks -q d3dcompiler_47' works around.

Tidbit, although not directly related to the HLSL shader compiler
insufficiency:

("WPF Render Thread Failures")

This also works around:

https://docs.microsoft.com/en-us/dotnet/framework/wpf/graphics-multimedia/graphics-rendering-registry-settings#disablehardwareacceleration

--- snip ---
$ wine reg add "HKCU\\SOFTWARE\\Microsoft\\Avalon.Graphics" /v
DisableHWAcceleration /t REG_DWORD /d 1 /f 
--- snip ---

You will have worse performance as the name indicates (if it matters), hence it
should be only used for debugging and testing purpose.

$ sha1sum Gaea-1.0.19.exe 
29ddfa3e404148babbae479153e438097077fb13  Gaea-1.0.19.exe

$ du -sh Gaea-1.0.19.exe 
41M    Gaea-1.0.19.exe

$ wine --version
wine-4.9-134-gd535df42f6
