 this as major. My two cents.

 Fine. I'm just trying to find a rational way to define ticket priorities.
 I was questioned earlier when "seems important, probably should get done"
 was my previous metric.

 > This is an interesting one. The patch comments out an entire block of
 //Mozilla extensions, but this section contains things like
 '_moz_windows_default_theme', '_moz_windows_compositor' and
 '_moz_windows_theme'. I reckon a combination of these removed features is
 responsible for the black control box and the transparency issues. It will
 take some time to figure out which ones.

 this block of features was the best course of action. I recommend
 rereading the source and revising this choice if needed.

 Yeah, word. It probably will require a few compiles on Windows to binary
 search it down to the exact rules that actually matter, or a few hours of
 wading through source. Though starting with uncommenting just the
 _moz_windows stuff and the blocks with min/maximize in it seems like a
 good guess to start.

 If someone who can actually compile our beast on Windows can narrow it
 down, it might help me to more easily hazard a guess.

 Setting this to "needs information" to reflect the fact that answers to
 these questions will help me fix it faster.
