Strange IP and BC bars on diplomacy screen
Please help
Hi all.
I'm new to the game and I'm still getting used to the mechanics of the game. Reading and watchint the tutorial videos have helped me much but I don't find any info about a strange thing.
When I click on "speak to" a alien race, I go to a "negotiation screen". There I can make offers or requests. I understand the mechanics involved but one thing. When I select influence points or credits, a window pops with a slider to select the amount to request/offer. But that slider bar has a green color gradient that ends before the full slider cap. It's like it was a gradient to fill the entire slider and is not well resized.
I post an image:

I started the game with a 4:3 windowed resolution just in case it was a widescreen bug but the slider remains the same, so it could indicate some kind of special level on that slider. Anyone knows about it?
Thanks in advance.
