Hello,

In my render loop I cycle through the textures used in the scene:

for(int texi=0;texi<textureCount;texi++) {
glBindTexture(GL_TEXTURE_2D, textures[texi]);
glDrawElements(GL_TRIANGLES, ... );
}

I'm getting wrong textures rendered in may batches unless I put a glFlush() in the loop, which makes it very slow.
My SDL2 G ES app works fine on PI 3 and many other platforms including XU4Q, Android, iPad

Any ideas?

The textures are fixed, if I call glVertexAttribPointer within the loop after each texture change. Is there a way to let the opengl driver makers know about this bug?

Maybe it's this one? https://bugs.freedesktop.org/show_bug.cgi?id=111052

That's right. Putting the latest MESA in Raspbian will solve the problem.
