Hang with Sparse Textures on Linux Driver

Creating a storage for a sparse texture 2D Array enough large, cause the driver stall for half a minute. Windows driver seems not having this behaviour.

Tested with 352.x and 355.x drivers series on GTX 750m.

This is the code i’ve used:

#include <GL/glut.h>

void
init(void)
{
  
    glPixelStorei(GL_UNPACK_ALIGNMENT, 1);

    GLuint TextureName;
    glGenTextures(1, &TextureName);
    glActiveTexture(GL_TEXTURE0);
    glBindTexture(GL_TEXTURE_2D_ARRAY, TextureName);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_SWIZZLE_R, GL_RED);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_SWIZZLE_G, GL_GREEN);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_SWIZZLE_B, GL_BLUE);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_SWIZZLE_A, GL_ALPHA);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_MIN_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_MAG_FILTER, GL_LINEAR);
    glTexParameteri(GL_TEXTURE_2D_ARRAY, GL_TEXTURE_SPARSE_ARB, GL_TRUE);
    glTexStorage3D(GL_TEXTURE_2D_ARRAY, 1, GL_RGBA8, 1024, 1024, 1024); // This instruction stalls the driver

}

int
main(int argc, char **argv)
{
  glutInit(&argc, argv);
  glutInitDisplayMode(GLUT_DOUBLE | GLUT_RGB | GLUT_DEPTH);
  glutCreateWindow("sparse Text example");
  init();
  return 0;
}
