[Mesa-users] Mesa 10.0.1 swrast: Setting XLIB_SKIP_ARGB_VISUALS=1 causes glxgears to be 45 degree shifted

[Bernhard Guillon]

Hi all,
we are using Mesa 10.0.1 swrast (on an ARM iMX31 with PowerVR MBX framebuffer support) to gain some OpenGL features. To enhance the speed we want to disable the composite feature of Xorg with XLIB_SKIP_ARGB_VISUALS=1. With the composite disabled the glxgears demo is 45 degrees shifted, with composite enabled everything looks fine :)



A demo application for a square looks like this:

With unset XLIB_SKIP_ARGB_VISUALS

         **********
         *        *
         *        *
         *        *
         **********

With XLIB_SKIP_ARGB_VISUALS=1

         **********
        *        *
       *        *
                        *        *
                       **********


Does anyone have any ideas what could be wrong?

Best regards,
Bernhard
