Unhappy Strange anti aliasing issue


Hi,

I have a pc in my office. This pc got a Asus mother board. There is a strange issue with graphics on that pc. Anything which I draw using GIMP or Inkscape is not smooth. If I open that file on other system and just save that with different name, it become smooth.

Earlier I thought its something related to graphic card. So I purchased a new graphic card (nVidia) but still problem is same. I also tried different OS (including Windows XP as system is on dual boot mode) but no luck.

I have attached 2 files. One is saved on that PC and another is from the same file, but I opened that file on second pc and saved that again.

Please suggest what could be the issue.

Have the various settings (openGL and others) been made identical?
Are there other OSes on one or the other machines? Doesn't look so much as antialiasing as a pixellation/resolution problem. So, I would make all settings identical and then compare again.

Thanks for your reply. Other machines have identical software configuration and display settings. Thats why its looking more strange to me too.

The pictures look quite similar here, but the strokes are different.
Just trying to be logical - if opening the file and rewriting it fixes this problem with no further issues, and the box is otherwise perfect, I would suspect
1. Software (libpng.so, libjpeg.so, gimp, whatever)
2. If you compiled plenty of stuff on one box, you could have the problem that your distro is expecting one version of a file, but 'make install' actually placed another version there. This is best solved by upgrading if you can't find it quickly, but can lead to insane faults.

Divide & conquer. If you eliminate gimp, or write .tiffs does the problem go? If you write jpegs does it return?
