Summary: Rendering bug due to ARB_texture_non_power_of_two Product: Mesa Version: git Platform: Other OS/Version: All Status: NEW Severity: normal Priority: medium Component: Drivers/DRI/R600 AssignedTo: dri-devel@lists.sourceforge.net ReportedBy: ppa...@shaw.ca While trying to address a D3D rendering bug report in Wine, I've been working on trying to add card recognition support into Wine for the Mesa ATI (R300/R600) drivers. This was in order to resolve a rendering issue when using the Mesa ATI driver. What we've found is that a code workaround to avoid using ARB_texture_non_power_of_two APIs on R300-R500 cards also seems to fix this rendering issue on Mesa DRI R600 (in particular with an HD4800 series card). This would seem to indicate a bug in the ARP texture_non_power_of_two implementation on R600. The Wine bug report is at http://bugs.winehq.org/show_bug.cgi?id=21515 Comments #45-47 indicate that the rendering problem is "fixed" by activating a "quirk"/workaround that avoids ARB_texture_non_power_of_two. Stefan Dosinger's comment #48 indicates what the "quirk" workaround does, how it should not be required on an R600/R700 series card, and how that indicates a probable driver bug. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. ------------------------------------------------------------------------------ SOLARIS 10 is the OS for Data Centers - provides features such as DTrace, Predictive Self Healing and Award Winning ZFS.
