[Bug 43504] New: tex2D() artifacts (tiling related?) on AMD RV670
https://bugs.freedesktop.org/show_bug.cgi?id=43504 Bug #: 43504 Summary: tex2D() artifacts (tiling related?) on AMD RV670 Classification: Unclassified Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: major Priority: medium Component: Drivers/Gallium/r600 AssignedTo: dri-devel at lists.freedesktop.org ReportedBy: kam1kaz3 at gmail.com Created attachment 54101 --> https://bugs.freedesktop.org/attachment.cgi?id=54101 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. -- Configure bugmail: https://bugs.freedesktop.org/userprefs.cgi?tab=email --- You are receiving this mail because: --- You are the assignee for the bug.
