Probably falls under the known issue described here:
Which Graphic card do you use? Do you have the latest Graphic card driver installed, please? Do you use HiDPI screen or not?
RTx3060 , works perfectly with C12 , everything’s up to date , this is the only visual bug i’ve seen Hdpi in normal mode enabled , please don’t start about graphics drivers , im not over the shite i went through with C12 YET lol
Sorry, I just try to help and find a solution for you (if there is any).
I updated everything just before installing C13 and just the studio driver ( restarted comp ), my Latency mon is still down on 55us Max
