Anyone have a idea what causes this..? It's always worked fine before.

   

Apparently someone else also using this terminal set imageshack to optimize any image into a six by six pixel .gif.

Much confusing, considering the original image was a .png.

No matter, I'll simply rig his bedroom to be flooded.

Added another image to show what it looks like on a freshly downloaded version.

Final Addendum: Nipped in to award Gobbo Overhyped Cavalry pointless poster kegcap and giant foam hand.

Hotlinking the thumbnail = fail!

Problem resolved. - Some setting on nVidia was incorrect.

Apparently DF uses Antisitropic Filtering.

Anisotropic.

[Cajoes]

Swedish spelling.

Edit: What's anisotropic?

It is the opposite of isotropic, which means "of equal proportions in all directions".  Anisotropic is not equal in all directions, like the 2:1 text size in dwarf fortress (and most other places, for that matter).

Did you change fonts/graphics sets recently?

When I was saving my fonts in the wrong bits (IE: 256, 64, 16, all the wrong kinds), this type of error occurred, but not nearly as weirdly.

This is definitely an nVidia setting that's causing this. Trying to pinpoint it in exactness has proven maddening.

It would be nice if there were some opengl option I could set for my textures or wherever so that this wouldn't happen, but I can't test it, so it's hard to figure out.  If I remember from the other threads, it was "high performance" or "texture compression" or somebody.

Generally, "high performance" is what causes the glitch. In this mode, nVidia optimizes their driver for maximum fps at the cost of image quality. There are a total of four modes: "High Performance"; "Performance"; "Quality"; and "High Quality". Despite these modes, some quality and performance features, such as anisotropy and antialiasing, operate independantly.

Worse, the optimizations are numerous, not well-documented, and are selectively implemented: The drivers have built-in presets for myriad (published) games so that optimizations can be engaged, or are prevented from engaging, when necessary. This is of course no help to a game such as Dwarf Fortress; Where no preset exists, the "performance/quality mode" is used as a fallback.

Where there exists no preset for the game or app you're running, the "mode" dictates what optimizations are engaged: All in "High Performance," none in "High Quality," and differing amounts in between. And from what I can tell, the parts in between are continually tweaked from one driver revision to the next.
