Just got the same issue.

It also blanked out Administration immediately to the left.

Can also confirm this.  Oddly, closing the window and reopening it "sometimes" fixes it.

Memory or video memory?  I had reloaded several saved games without exiting LH, which I remember caused memory leakage in the FE beta but I thought had been fixed.

Variations of this happen to me randomly in FE as well

Happens to me, too. I have a very powerful card and system, too. 

the best i've been able to tell is that it happens to me after a long period of having the game running.  for me it's a couple of hours of play or if i left the game on while i was doing other things with my family. 

I really don't think this is a memory issue.

System Memory: 16GB
In use at time of bug: 11GB

GPU Memory: 4GB
In use at time of bug: 1.4GB

I just fired up LH fresh, after closing out of Steam completely.  Started off by opening a saved game, everything looked fine.  I checked all three branches of research and dragged each one of them around, all the tech titles moved with their icons correctly, none were missing.   Without doing anything else in that game, I simply loaded the same saved game file again and upon that second time, I saw the issue.  2 labels were completely missing off techs in the Civilzation tree. 

*Edit*

And I've just reproduced it now following the same steps.  Close out of steam completely, restart and launch LH.  Upon first time of loading a saved game, the tech trees look fine.  Upon second load (from within the game), the bug is happening again.   

*2nd Edit*

Game was running at 4x AA, which I had dropped it down to by request from Stardock.  I could drop it to 2x and keep testing for it, but I'm thinking it unlikely to matter.  Let me know. 

I will note, I had already dropped my AA down to 4x during the above testing.

My AA is set at 2x, so I don't think that's the problem.

That looks like an early game, did you use Ctrl-N at all to get a decent start? I know that also causes it, it's basically doing the same thing that makes reloading cause it. They don't clear everything from memory when you Ctrl-N or reload a save, in fact they keep most of it loaded, probably so it will reload faster, but this is one of the many issues it causes.

I've never seen this happen in a game I haven't reloaded or used Ctrl-N on.

Another likely way to cause it is to load a game, exit to the menu, then start a new game. I imagine that works much like Ctrl-N. I haven't tried it though.

Yeah I get this, definitively from using Ctrl-N.... possibly when going back to the Main Menu and starting a new game also.

Yep I just got this again too.    

@Kael - any ideas on this one, it's really nasty 

I did this after the last patch, will try it again though good suggestion.
