Hi, I've found a bug. I talk about here : https://forum.studio-397.com/index.php?threads/white-screen-with-all-tatuus.65597/ Now I know how to reproduce it. At Adria with Tatuus F4 (and others) or Imola 2018 (rieza pack) with Bentley. When I set the "Transparent trainer" parameter in "Display" setting at "Best" or "Saved". No problem if this parameter is set at "Off". But it seems to me before I erase my data that I had a ghost for the bentley on imola and I had the blank screen anyway.
