Contents of RTT
After some more messing around I have proof that the problem is when rendering to the texture. Not when reading from it.
See attachment.
The bug was on my app. Sorry. |

Created attachment 54101 [details] Screenshot showing problem This is what I'm doing: 1) render scene to render target texture A 2) render quad on screen to show RTT A data When on the second step, I am using a fragment shader that calls tex2D() to retrieve the RTT color data, however I get artifacts as shown on the attached screenshot. Whenever I restart the application, I get different corruption. I'm not sure the problem is when reading from the texture, or writing on it. If I output colors without using tex2D() it all works fine.
