This is a visual bug. Appears when displaying a technology image from a simple mod, like this one.

Here is the mod for testing/viewing of the bug: http://www78.zippyshare.com/v/Kh1A3clx/file.html

Attached is a picture demonstrating the bug. Note that the technology image is a copy of the one that the base game displays.

Location RED Circle: The technology image wasn't resized to fit the UI size, unlike the base game images.
Location BLUE Circle: The technology image is drawn at twice its size. (it's stretched partial image)

That's all for now. I hope that this gets fixed asap.

Without a fix, mod technologies end up looking stretched at the blue location, when the mod uses the older 64X64 image size.

Not a bug;

In your technology definition you need a line saying " icon_size = 128, " as the icon you're usign is sized 128x128 (default size is 64x64)

Thanks, Klonan.

Turns out we have an omission in the base game lua.. 128x128 default value for the base lua while mod lua has a 64x64 default, which made me look at it like that was a bug... anyway, that fixes it. (A list of accepted properties and their defaults would be nice I suppose..)

So while it may not be a bug it's definitely derping up the icon for the mod even though its pretty much a copy of the base chemistry.lua.
I could be blind though.

The point is, it's confusing.

Just looking at the documentation, class LuaTechnology, I don't see what it inherits, so I've got no idea.

Anyway.. that's all for now.
