Dear all, after a Carbon Copy Cloner I completely initialized my SSD internal drive and installed Mojave. I upgraded from Mavericks and thought that was the right time to a new installation after coming to HS with upgrade. I'm experiencing typical GPU glitch in Mojave on the right side of my 32" LG monitor. Nothing similar in High Sierra. The strange thing is if I use the built in register function in Mojave to show you I can't get glitch... Sometimes they happen also during mouse move or keyboard press. Haven't had any problem at all in High Sierra, like GPU hang or similar. Thanks a lot for any hints Claudio.
