Hello,
for some reason my ATI Radeon HD 5850 seems to have problems with...
GL_DEPTH_COMPONENT16
GL_DEPTH_COMPONENT24
GL_DEPTH_COMPONENT32
GL_DEPTH_COMPONENT
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!
- Windows 8.1 but also happens on Windows 7
- Catalyst version 13.12
- I use core profile 3.2
