Subject: [Bug 26525] New: Rendering bug due to ARB_texture_non_power_of_two
Date: Wed, 10 Feb 2010 20:48:40 -0800 (PST)	[thread overview]
Message-ID: <bug-26525-502@http.bugs.freedesktop.org/> (raw)

http://bugs.freedesktop.org/show_bug.cgi?id=26525

           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: ppanon@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.
