Just to make this clear, it's gotta be a bug in wine causing malfunctions in
Source's multicore renderer -- I'm quite sure that it's not a bug in the
engine.

However, both issues mentioned here (i.e. "penetrating lights" and "invisible
tooltip text") *could* be caused by some kind of missing synchronization
between two rendering threads, so things are rendered in the wrong order. That
is:
- Lights after geometry obscuring them
- Some letters in tooltips prior to the tooltip's background

But after all, these issues being related is just a guess...

Moreover, debugging this might be really horrid: I assume it would come down to
comparing d3d/d3d9 traces between single- and multicore rendering mode. That's
a *huge* bunch of data and manual work... and I'm not too sure this approach
could succeed at all.
