Hi Timo, This does not fix the issue for me (assuming its the same issue). I have a phantom duplicate display shown for each of my external monitors which only occurs when I use a thunderbolt cable to my Apple Studio Display (27¨) or a similar cable (OWC Thunderbolt) my Lenovo p27-10u 4K display. When i switch out cables for standard USB-C 3.1 cables, all works fine and no phantom monitors show. I have tried only one monitor on USB-C and one on Thunderbolt as well and only the Thunderbolt connected monitor has the phantom problem.
This behaviour is consistent before and after testing with the updated ubuntu-drivers-common/1:0.9.7.6ubuntu3.2 patch which is proposed. I tested this before and after subsequently installing nvidia-driver-535 (although Iḿ not sure what NVIDIA has to do with my system with intel integrated graphics). My system is a Lenovo T14s (Gen 5) Intel. (Intel Arc Graphics) + LUKS encryption. I have very limited time today but see you provided some links above. Happy to provide any more info / logs etc if helpful. I could not find another bug relating to thunderbolt but am happy to log one if this is a different issue as it was unclear to me whether thunderbolt has been taken into consideration with this issue. I would appreciate your guidance whether my scenario is related and what my next steps should be to help.
