is that relation certain with a regwindow or still in need of confirmation. I'm adding the keyword, change it accordingly.

I can confirm this on my build: Mozilla/5.0 (Windows NT 6.1; rv:2.0b8pre) Gecko/20101213 Firefox/4.0b8pre ID:20101213030326

I can confirm using:
Mozilla/5.0 (Windows NT 6.1; WOW64; rv:2.0b8pre) Gecko/20101213 Firefox/4.0b8pre ID:20101213030326
...so changing platform to All.

STR:
1) Create clean profile.
2) Visit a few sites to populate history/give something for awesomebar to show.
3) Set hardware acceleration to off in prefs and restart Minefield.
4) Press ctrl+T to create a new tab.
5) Give awesomebar focus, but make sure mouse cursor not hovering over where the dropdown will appear (or the highlight comes back).
6) Type characters from the site URLs visited in step #2 to make awesomebar dropdown appear.
7) Press down arrow to cycle through shown awesome bar results.

Expected:
- Highlight appears over currently selected row in the awesomebar dropdown.

Actual:
- No highlight as the down arrow is pressed, unless the mouse hovers over the dropdown at the same time.

NB: Issue seems to only occur when hardware acceleration turned off.

Of the changesets in that pushlog, only 4 are not tests or strings, and out of those left I would presume bug 615870 is most likely? (Given the rest are plugins/addons/doorhanger CSS margin related)

Provisionally marking as blocking bug 615870 for visibility over there.
