Priority: medium Bug ID: 81689 Assignee: dri-devel@lists.freedesktop.org Summary: Black screen in info-beamer Severity: normal Classification: Unclassified OS: Linux (All) Reporter: sa@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=cef11b335be2741058363...
The trace renders correctly but gives a lot of errors, so this might be a bug in info-beamer:
