Low Res KitKat Launcher Icons
Take a look at the large version to see the icons better. If you zoom in, you can see that the icons on the stock KitKat launcher are definitely blurrier than in third party launchers (in this case, nova). The low icon resolution is really obvious when viewed on the Nexus 4 and is ruining the otherwise great experience of the new launcher for me (with the exception of that damn persistent search bar). I've seen other reports about people experiencing the same issue on other forums, but none have been able to produce a solution. Hopefully Google can fix this soon.
