What
When you open the tech tree and subsequently open the console, the text input part of the console is visible over the tech tree, but you can not type in it. The log of the console is visible(just) behind the tech tree.
I'd say either the input should be put behind the tech tree gui, or the console history should be put over the gui.
The console can also not be closed in the tech tree

Steps to replicate
1 open tech tree(any way works
2 open console

Thanks for the report, this issue has been present for some time now.
From now on, there will be a change in behavior. In general, console will not be invokable when game is paused. That includes technology window in single player, as that pauses the game. In multiplayer the console will work correctly.
