Assuming "wrong rendering" refers to this paragraph from the referenced
bug you reported:

 However, that could produce incorrect rendering with intermediate
 flushes and some operators that cannot easily split (e.g. Out).

That would be a client bug, the RENDER specification explicitly defines
how rendering is performed when mask-format is None.

So, this is quite certainly the correct fix.
