--- Comment #2 from Christian Costa <titan.costa at gmail.com> ---
I remember investigating this issue few years ago. It seemed
D3DXGetImageInfoFromFileInMemory should return D3DFMT_A8R8G8B8 instead of
D3DFMT_X8R8G8B8. I didn't find a clear way how TGA files are supposed to
advertise if an alpha channel is present or not for 32 bpp and how
windowscodecs.dll handles this.

Maybe there's something similar to a patch in wine-staging where
D3DFMT_A8R8G8B8 is returned when at least 1 pixel has a non zero alpha
component.

The patch fixes the cursor transparency in Runaway 2.

Tests were upstreamed:
https://source.winehq.org/git/wine.git/commitdiff/a30fd8c0e44833b2a6412987a348273bfe42fe2f?hp=ccdb74d81ac4a95aa87414f6459a8b44d451358a

Fix is still in wine-staging:
