  • Requested reviewers:

Reason why this change is needed

  • CLANG 18 MSAN reports use of uninitialized value in renderer flush
  • if no samples are to be flushed out, nothing is actually copied, but still the function is called and the uninit pointers are accessed

Description of the change

  • initialize pointer array always, not only if there is something to flush out (init is anyway independent of channel num or other runtime vars

Affected operating points

  • None
