Problem 5, Terraria now no longer crashes, but looks like this:

Solution: ??? Is this the end of the line?

It's a bit off-topic, but I must thank you for providing an insight for my own problem. I've just updated from 1.4.0.5, and your screenshots are what Terraria 1.4.1.1 looks for me. Everything is flickering rectangles -- sprites, letters, cursor, everything. But now that I know it's an FNA issue, I was able to rid of this graphics glitch by downgrading FNA.dll to the one provided with 1.4.0.5, and the game seems to work fine. Not the most elegant solution, but I'll take whatever works.
