    ATI / AMD depth texture issues when using GL_DEPTH_COMPONENT




      for some reason my ATI Radeon HD 5850 seems to have problems with...







      When I create an FBO with only a depth texture attachment...


      glTexImage2D(..., 0, VGFX_DEPTH_COMPONENT, Width, Height, 0, GL_DEPTH_COMPONENT, GL_FLOAT, NULL);


      ...and I use glBlitFramebuffer to copy the depth texture to another compatible texture

      which is rendered to the screen I get strange results, some diagonal lines

      (see attached Bild2.jpg and Bild3.jpg).


      But when I use GL_DEPTH24_STENCIL8 instead, everything looks fine (see Bild1.jpg).


      What is wrong? There are no gl errors and the frame buffer status is complete.


      Help is really appreciated!

      - Catalyst version 13.12

      - I use core profile 3.2
