is this vector map from Locus store? Does it happen with internal themes?
I've tested the last vector Poland map and it looks OK (from point of view of the map or themes).
You got me :) yes it is the latest from store (yesterday download) but theme is not internal :) with internal all is ok, so... i have to leave those themes? Earlier it was good :(
It seems that you use themes from OpenAndroMaps - I've tried these themes and I also facing this issue with blue squares. Honestly I don't have any clue why it happens. Blue rectangles can appear due to wrong handling of sea areas but internal themes and OpenAndroMaps themes use the same workaround for correct rendering of the land and see. I'll try to find out more...
Problem solved, please install or download the themes from
Thanks Christian for quick update.
