Seems to be fixed in recent mesa checkouts - so marking as fixed

[Bug 8489] New: Blue patches in textures with r300

Please do not reply to this email: if you want to comment on the bug, go to    

the URL shown below and enter yourcomments there.     

https://bugs.freedesktop.org/show_bug.cgi?id=8489          

           Summary: Blue patches in textures with r300
           Product: Mesa
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: major
          Priority: P2
         Component: Mesa core
        AssignedTo: mesa3d-dev <at> lists.sourceforge.net
        ReportedBy: z3ro.geek <at> gmail.com

I get blue patches in textures after the following commit:

try to use a 8888 texture format which will result in only a memcopy in mesa's
texstore functions whenever possible for r200 and r300. r200 can use hw formats
argb8888, rgba8888 and abgr8888 (or the opposite on big endian), r300 can use
argb8888, bgra8888, rgba8888 and abgr8888 regardless of endian, as it supports
free component swizzling.

I'm not sure of which CVS commit this is, since I imported Mesa CVS into a Git
repository so I could use bisect. I wasn't aware of the Freedesktop Git mirror
at the time.

I guess I'm responsible for this...

I can't see any reason why using arb vp/fp would make a difference. I assume
this is on little endian (x86)? If you could run glean's pixelFormats test, this
should show what combinations of src and internal format are failing.

We could add a new mode to the pixelFormats test to use a simple fragment
program when drawing the test polygon.  That might be interesting.

I assume this is native 64bit? I'm not sure, but maybe pixels might end up
swapped somehow, which the glean pixelFormats test would not detect (at least
not if they are only swapped pair-wise).

Yes, it's all native 64bit. I'm using a GPL licensed engine, actually a
modified Quake 3 that I modified some more, so it's all compiled natively for
x86_64.

Might be a good idea. I'll happily test with it if you provide a patch to add
this test.

OK, update your Glean tpixelformats.cpp file and set USE_FRAG_PROG to 1 before
compiling.
