Comment 11 for bug 1218815

It's been suggested we have an incorrect stride value for scanout buffers (even when they're not being scanned out). That would certainly agree with the screenshot in comment #5. So I think a fix is required via mir_surface_get_current_buffer() ?...

_X_EXPORT int32_t
xmir_window_get_stride(xmir_window *xmir_win)
{
    MirBufferPackage *package;

    mir_surface_get_current_buffer(xmir_win->surface, &package);

    return package->stride;
}
