 Posted: Tue Feb 17, 2009 1:50 pm Post subject: opengl quirks with open source ati (radeon) driver |
 |
|
Hello all. I have to premise that nothing I'm going to describe was happening with the closed source drivers (ati-drivers). I'm also quite reluctant at the idea of going back to the closeness, so I'm hoping you may have some answers for me.

The first image shows the 2D Painting demo from Qt and the problem seems to me quite obvious. The second one shows an app of mine in which I paint things inside an opengl viewport and those green boxes should actually be lines (green, of course). This thing with the lines only happens when I set the line width more than 1... I've not been able to determine some sort of pattern, this is just what I'm getting.

| In the end, I reverted to the closed source driver since I found the open source to be less mature than I thought. I'll keep an eye on it but for now ati-drivers is the best choice for me. |
