UPDATE - Downgrading to Sequoia fixed all glitches!!!
Earlier today I installed the newest public beta of MacOS Tahoe, once turning my MacBook on there was a weird flash glitch that kept occurring (as shown in video). A few months back I installed a new replacement screen that I bought on amazon (third party brand) this glitch would occasionally happen but would go away once I restarted my Mac and was barely noticeable. I already tried downgrading my MacBook to an earlier version of Tahoe, but this hasn’t fixed the issue. I’m currently trying to downgrade to Sequoia to see if that will help fix this issue. This weird flash glitch is actually the most annoying thing i’ve had to deal with on my mac :/ If anyone has any tips it would be very appreciated, Thanks!!!
