Does anyone know if there is ever going to be a GLX equivalent to WGL_ARB_buffer_region? I know that mesa has ktx_buffer_region, but that one is a bit ill-specified.

I think you mean GLX_MESA_copy_sub_buffer. This doesn’t offer quite the same functionality as the WGL extension, but it is fairly close. As far as I know, that’s is the closest extension available for GLX, and no hardware driver supports it.

You may want to contact the developer support about this. They can then bring it up with the ARB to get an extension created.

Only KTX_buffer_region(it is supported by NVidia h/w accelerated driver):slight_smile:
