--- Comment #6 from Toni eldrad@autistici.org --- You could change the title of this issue to:
"Shadow Tactics displays a pink screen (d3dcompiler: syntax error, unexpected KW_CBUFFER)"
Also the component for this bug is definitely d3dcompiler
I guess there can be more errors on the d3dcompiler after this one but we won't know until this is fixed, changing the title can help in getting a developer into it since the possible fix will be more evident on first view on the bug listing (I think this is for Matteo Bruni since it looks like he coded wine's d3dcompiler).
