Annoying login bug

This started after an update several weeks back. The initial 'splash screen', (the one with the picture of a settlement and the Ubisoft logo), now appears for a second time, and sticks itself behind the 'tip of the day' screen. Most of the time this just slows down the loading of the graphics on the island, but occasionally it causes the drawing to freeze, neccessitating a refresh, and this also seems to have been the start of the 'white screen' on login too, which sometimes takes a number of refreshes to unstick. Both seem related to the splash logo, and the perennial clearing of cache, etc... does nothing to prevent this, nor does changing browsers.
Think there is some corrupted code in the splash screen.
