Priority: medium
Bug ID: 81689
Assignee: dri-devel at lists.freedesktop.org
Summary: Black screen in info-beamer
Severity: normal
Classification: Unclassified
OS: Linux (All)
Reporter: sa at whiz.se
Hardware: x86 (IA32)
Status: NEW
Version: 10.2
Component: Drivers/Gallium/r600
Product: Mesa
The multimedia presenter info-beamer ( http://info-beamer.org/ ) just renders a
black screen with r600g.
It's working fine with software rendering and on Intel hardware.
Not a regression, or at least present in Mesa 9.2.
I've made an apitrace of one of the beamer demos:
https://my.owndrive.com/public.php?service=files&t=cef11b335be2741058363783176b14cd
The trace renders correctly but gives a lot of errors, so this might be a bug
in info-beamer:
0 87813 glGetUniformLocation(program = 0, name = "Color") = -1
87813: warning: glGetError(glGetUniformLocation) = GL_INVALID_VALUE
87872: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glReadBuffer(buffer=0x405)
87872: glDebugOutputCallback: High severity API error 1, GL_INVALID_OPERATION
in glDrawBuffer(buffer=0x405)
