Thanks for the note. But mine, official 15.0.1, still definitely have the screen flickering issue (on a dark grey solid color background).

I had same problem since updating to Sequoia yesterday. I called apple support. What seems to have fixed the problem (at least for now):


Start up your computer in Safe Mode. If you do not have the flickering while in Safe Mode, it is a software problem. That is what they told me. If that is the case the next step is to reinstall Sequoia. See the link with the steps for starting up in Safe Mode and for reinstalling Sequoia. They told me I had to do the safe mode thing FIRST. The first time I called, the person asked me to re-install, but did not ask me to start up in safe mode. That did not work. I called again and the other person told me I had to start in safe mode first, and then reinstall. It has been about two hours that I have done these two steps and so far no flickering or flashing or sliding the screen from right to left.
