It's similar for me, but my tab previews are the various tabs' favicons.
In addition it also affects if you have other Firefox windows open. Only if the option is enabled.
Yes, I can reproduce. Looking into it.
I backed out bug 515907 and the problem still persists, plus that bug doesn't really touch the part of the code that generates previews, so I really doubt it's that.

mwu, could your PRBool to bool change have caused this? See <https://hg.mozilla.org/mozilla-central/diff/e7854b4d29ba/widget/src/windows/TaskbarTabPreview.cpp>.
Yep, I'm pretty sure that's the reason.
Depends on: 675553
No longer depends on: 515907
Attached patch patch v1Splinter Review
Yep, fallout. We didn't catch this because we were assuming (and not type checking) that PRBool = BOOL.

I just grabbed the Nightly hourly (C-set ID 164fd1bbd06f) containing the needed patch and can confirm that Win7 Taskbar Previews have been fixed.

Thanks for the fix. Sorry for the initial misdirection. Just think of it as a little test. ;-)
No worries: my patch was the obvious one to blame.
