Some further findings: the critical part seems to be whether
IWineD3DImpl_CheckDeviceFormat succeeds for 16 bit format like
WINED3DFMT_A1R5G5B5 with WINED3DRTYPE_TEXTURE rtype and
WINED3DUSAGE_RENDERTARGET usage. Before that commit by Roderick it apparently
was succeding. After it, this call returns WINED3DERR_NOTAVAILABLE. Which, on
first sight looks like it's correct. So maybe the real bug is not introduced by
Roderick's comment but exposed by it. Interestingly, the game also checks other
texture formats with rendertarget cap, some of which succeed. I would guess
that maybe the app prefers 16bit, so if it sees WINED3DFMT_A1R5G5B5 then it
chooses it and something different happens from what happens if it chooses some
formats for which IWineD3DImpl_CheckDeviceFormat succeeds (like A8R8G8B8).
