Introversion

Just unpack main.dat and rescale the textures to 512x512.

Resizing the textures to powers of 2 didn't help.

I'm having the exact same problem. I have an ATI Radeon IGP 345M and am using Ubuntu 9.04.
I even changed the mouse image in main.dat, but it still showed the same big white cursor over the map, so it seems to somehow take the texture from the normal mouse cursor.

I'll post more info later when I'm back on my own PC.

Note: I also have some random graphic glitches with the world map in Uplink.

Try smaller texture sizes, like 256x256. That's all I can think of apart from bugging the driver authors to have a look at the problem.

Well, the introversion devs could also just code in a texture resizing function into the game... (or ship it with alternate power of two textures)

A lot of openGL games run well on my PC (including Darwinia), so I believe it's possible to solve this problem without changing drivers.

That's what we did for the GP2D engine (altough it seems to have changed now): http://gamepower.sourceforge.net/en/index.php
cf also: http://code.google.com/p/pygl2d/issues/detail?id=1
(both GPL, but it shouldn't be too hard for introversion devs to code something like that. )

But if the mouse texture is power of 2, then it must be another problem. I'll try to find out as soon as I can.

Don't hold your breath for code changes adapting Defcon to your hardware, especially not if making the change you request (resizing the texture) manually doesn't work.

Ok, so it seems I made a mistake the first time and the original textures were used:
I extracted the contents of main.dat, modified them and recompressed the archive.

However, there was a normal data folder in the lib directory which contained the original images (earlier extraction attempt I think).

Anyway, I fixed this and this time my modified cursor showed up, meaning the power of two textures were used.
The bug was still there, so it's unfortunately not just a NPOT texture problem.

Glitches I experience:
-When I middle-click on the map to move it, a font grid appears.
-I also see the font grid in the join game dialog instead of the world map.
-My current cursor (arrow or moving cross) is always superimposed on the world map during play.
-Moving the mouse over units/buildings changes their texture (ex: fighters become missiles)
-Some units have the wrong texture (ex: silo looks like a nuke)
-Yellow flickering onscreen

Is the code for defcon available somewhere? (like the code for Uplink for example)

Defcon version: 1.42

My glxinfo output:


P.S.:
Just in case others would like to try out resizing the textures, here's what I used:


The ~/bin/POTify.py script to resize an image to the next power of two if necessary (requires imagemagick):

First bit of advice: DO NOT rar the data directory. Defcon will read directly out of the data directory, so there is no need to rar it, and there is the potential to cause problems (i.e. by not raring it correctly, or by still having data in the data directory).
