Looks like a Safari issue or driver or both.
Is GTX 1080 Ti stable on your system? Any crashes, freezes, kernel panics?
Thanks for the hint, I would say so, but I'll have to check, I'm away from the office for 2 days, I'll check it as soon as I'm back!Do you have up to date Evergreen and Lilu kexts?
My lilu indeed was not up to date, I had 1.3.1 - I'm updating it right now...Do you have up to date Evergreen and Lilu kexts?
Breaking news!
I've just update to 387.10.10.10.40.122 which was very recently released and it seems like everything works fine and better than 378.10.10.10.25.106, I never got the previous 387.* versions, so I'm really happy now!
