Since you mentioned rendercheck I gave it a whirl, and I did see that the "Window format" shown for turbo was r5g6b5, while for tiger it was r8g8b8. So I switched -depth to 24, and the warning about RENDER went away ... Seems odd to complain about render in that case, but that seems to clear it up :-) On Monday, February 22, 2021 at 12:52:11 PM UTC-8 DRC wrote:
