Sorry about the delay. It happens every time you start the browser when the phone is connected to WiFi but the WiFi is not connected to the internet. The example I provided: at the supermarket, on a known network, but waiting for enterung the login details, is the most obvious but it is reproducible at will by e.g. disconnecting your hone WiFi router from the internet.

It affects bookmark icons created from favicons rather than from the miniaturized screenshits and appears in three stages:

1) First, the icons appear only as black squares.



2) After a certain timeout, which I have not figured out, the black squares are replaced with the notorious stars.



3) Once the internet connection comes back again, the icons are refreshed properly.



It has been like ever since I remember and is still like that in 1.1.6.xx. I really wish the icons were downloaded once when the bookmark is first made and left be.
