           Summary: [r300g] Compiz fails to start using gallium on rv350.
           Product: Mesa
           Version: git
          Platform: Other
        OS/Version: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/DRI/r300
        AssignedTo: dri-devel at lists.freedesktop.org
        ReportedBy: oreaus at gmail.com


Compiz will only start with GALLIUM_ABORT_ON_ASSERT=0 or it crashes. I bisected
and on current master 7ed2f953c0b109d35ddb4c58effb18bd0fac4592 the message is:

r300: Implementation error: Format mismatch in r300_surface_copy
    : src: b8g8r8a8_unorm dst: b8g8r8x8_unorm
r300_blit.c:134:r300_surface_copy: Assertion `0' failed.
debug_get_bool_option: GALLIUM_ABORT_ON_ASSERT = TRUE

while with the first bad commit found 968bf9634ec03e61441834603f13f0c914bbb0ce
the message is:

r300_blit.c:136:r300_surface_copy: Assertion `dst->texture->format ==
src->texture->format' failed.
debug_get_bool_option: GALLIUM_ABORT_ON_ASSERT = TRUE

This last good commit is: 821abff8c03031603111abc17dabe7cfa28a31e1

I will provide any further requested information.
