fallback). As for lesson20 I have no idea - try commenting out drawing code and checking which part creates a lockup.
Btw, I am getting a partial lockup with lesson20 even without r300_dri.so (when it is absent the driver falls back to software rendering), so it might be due to mode switching.
Lesson 20 have 3 points that causes lockups (maybe more). They are all related.
the first is at line 258-259: glBindTexture(GL_TEXTURE_2D, texture[3]); glBegin(GL_QUADS); glBegin() is causing the lockup, but only when textures 1, 2, or 3. if you change it to texture 4: glBindTexture(GL_TEXTURE_2D, texture[4]); glBegin(GL_QUADS);
The lesson will now run (until you press space). To me it sounds rather strange that a texture causes the lockup.
This is indeed strange.. Is texture[4] used anywhere before ? Does the same happen with latest CVS ?
thank you !
