Hey I just tried the latest 0.0.12 beta release again.
The app booted up normally. Console was clean no errors. So I hit refresh and the whole screen goes blue, that is color-positive blue (now scared) I again refresh and the app boots up normally clean and error free. But to be sure I refresh again and now again the screen turns blue. And I refresh again and the app boots up normally. :smile Blue screen and normal rendering occurs at alternative refreshes. I cleared cache, history everything. It is still the same.
If I inspect-element the blue screen I notice that it is a property on the body tag with background set to blue and no other properties are visible. All my unit tests fail in 0.0.12 but they pass on version 0.0.11. I am having this problem now. Both on stable and nightly build of 0.0.12.
