So i have redone my OCLP install with Sequoia on my iMac when I installed an internal SSD, and now the machine does this weird thing.

I put it to sleep and it would stay like that but randomly I notice the screen’s backlight goes ON (no image on screen just black) for a while and then back off. It’s not awaken because if I move the mouse when it does that, nothing happens, actually trying to wake it up from that state doesn’t really work until it decides to turn the screen off. The duration of this “backlight glitch” isn’t always the same (some times it lasts long, sometimes it does not)

I have zero idea about what could be happening here but it’s really annoying. It definitely wasn’t happening when I had an earlier version of Sequoia running on the same machine but with the spinny drive.

Any help appreciated.
