I'm playing in 1280x1024. I guess its well known that the pick screen doesn't display properly in this resolution (there is a gap at the bottom where you can see the interface panel and part of the real minimap).
However, with the last pick UI rework, the minimap where you can place your hero icons doesn't respond to the clicks on the right side. As a result, its very hard to place your icon on Dire offlane, and somewhat in Radiant safelane.
On the screenshot, areas to the right of the red line can't be clicked.
