GL_CLAMP changed to GL_CLAMP_TO_EDGE this doesnot help.

All scraps commented. It makes GL work a little fast, and some pixels looks like in original image. But it not help too (.

Did you know quake/hexen2 engines where this bug fixed?

Yes, i am new to OpenGL =). Thank you very mach, now i have blending, alpha test completely removed. And after that, EDGE lines (one pixel of padding? ) become less visible, but not fully it fix problem, lines Thinned.

I am sorry about your traffic, i am know jpeg, but i am not used it in this case because jpeg can loss these buggy lines. (My bad i should first try)

EDGE lines (one pixel of padding ) presented not only in 2d HUD's etc.
but in 3d world itself, some textures have bad alligment, this is not happen when i use software mode, or i open this image/texture in viewer or in photoshop.

I am post later new screens in jpeg of course

Texture sizes need to be a power of 2 (2, 4, 8, 16, 32, 64, 128, etc) and the engine will resample them if not. Look at FitzQuake for a way around this; it pads HUD textures out to a power of 2 size so that the quality doesn't degrade.

Ok, thanks. I am look on it.
I forgot to say.
I am already added GL_TEXTURE_NON_POWER_OF_TWO support, maybe i am makes some mistakes? I upload source code and my hexen2.exe compiled file.

Even GL_NPOT doesnot help to remove (bad padding of textures, positions, offsets?), this makes textures looks like original (no resize operations, and way less pixilated), and decrease memory usage.

npot obsoletes what mh suggested, yes. At least for cards that properly support npot.
clamp-to-edge will not work correctly on scrap images, as the edge isn't where it ought to be.
gl_texturemode gl_nearest? ehe
Failing that, you can adjust your texture coords in by half a texel, depending on resolution.
