Sorry for not clarifying. The screenshot is not my boot screen. The system boots up into EOS fine but only issue is the display’s weird doubling effect. This screenshot is lorem ipsum text on a text editor to show my screen’s state (I will clarify it on my post description). I did what you said, hooked up my laptop to an external monitor and everything looks fine on the monitor screen. So the issue is only with my Laptop’s screen I guess. Also yes, the doubling glitch is present on the bootup screen, BIOS screen. Unfortunately I don’t have timeshift.
