Subject: [Bug 42435] New: Suspected loss of varyings between shaders
Date: Mon, 31 Oct 2011 14:40:48 +0000 [thread overview]
Message-ID: <bug-42435-502@http.bugs.freedesktop.org/> (raw)

Bug #: 42435
Summary: Suspected loss of varyings between shaders
Classification: Unclassified
Product: Mesa
Version: git
Platform: x86-64 (AMD64)
OS/Version: Linux (All)
Status: NEW
Severity: major
Priority: medium
Component: Drivers/Gallium/r600
AssignedTo: dri-devel@lists.freedesktop.org
ReportedBy: screwdriver@lxnt.info
Longer description, the test case, screenshots, and core from i965 crash are
in attached archive.
In short:
I try to draw a 2D screenful of point sprites, emulating an ansi-colored
terminal. Fragment shader receives texture coordinates for the character, its
color and size of graphic in the texture via varyings.
R600g draws a black screen, while llvmpipe and fglrx draw what is supposed to
be drawn. i965 crashes. non-llvm swrast fails to set gl_PointSize. R600c also
draws a black screen.
Drawing varying values themselves I get bogus values for some of them.
Mesa version: 7.12.0~git20111027.0fbc8d30-0ubuntu0sarvatt~natty
