Summary: [r300g] Oilrush: whiter triangle between center of the screen and horizon Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: minor Priority: medium Component: Drivers/Gallium/r300 AssignedTo: dri-devel@lists.freedesktop.org ReportedBy: pavel.ondracka@email.cz
Created an attachment (id=45121) --> (https://bugs.freedesktop.org/attachment.cgi?id=45121) terminal output
There is a strange triangle of whiter area and missing effects between screen center and horizon in Oilrush.
I'm attaching terminal output, however I don't think there is anything important, just a few of:
Mesa warning: glDraw[Range]Elements(start 130, end 877, count 1650, type 0x1403, indices=0x1c2) end is out of bounds (max=876) Element Buffer 31 (size 3750) This should probably be fixed in the application. and
Mesa: User error: GL_INVALID_VALUE in glTexSubImage2D(xoffset+width) OpenGL error: invalid value
However both of those errors are also present with llvmpipe which renders fine (not 100% fine, but this bug is not present there). RADEON_NOT_TCL=1 also solves this issue, where READEON_DEBUG=noopt has no effect.
BTW you need to set MESA_EXTENSION_OVERRIDE="-GL_ARB_draw_instanced" when using llvmpipe of software TCL otherwise you run into other troubles like:
GLShader::loadVertex(): error in "core/shaders/default/meshes/vertex_base.shader" file defines: UNKNOWN,QUALITY_LOW,MULTISAMPLE_0,USE_INSTANCING,USE_TEXTURE_3D,USE_ALPHA_FADE,USE_ENVIRONMENT,OPENGL,USE_PSEUDO_INSTANCING,USE_PSEUDO_TRANSFORM,HAS_ARB_DRAW_INSTANCED,BASE_AMBIENT_REFLECTION_CUBE,AMBIENT,PAINT,OPACITY,MULTIPLY_0 0:194(39): error: `gl_InstanceID' undeclared 0:194(42): error: Operands to arithmetic operators must be numeric 0:194(19): error: cannot construct `ivec3' from a non-numeric data type 0:194(58): error: Operands to arithmetic operators must be numeric
and almost no rendering at all.
