The "spooky" Aero Glass watermark under the start menu and action center seems to be fixed. I don't see it anymore. Firefox 43.0a1 Nightly is not being handled by Aero Glass properly, the entire window border is grey instead of transparent, it's been like this for a while. I checked in Windows 7 and it's not grey when using that but maybe it's a Windows 10 thing, the developer theme actually looks better in Windows 10 then Windows 7 (reminds me a bit of Edge). Btw, I saw (a bit late) that Windows 10 Insider Preview Build 10525 is out, haven't tried it tho'. Anyone know if Aero Glass works with that?
