That screenshot is now gone, but here is a similar post: https://forums.freebsd.org/threads/distorted-image-in-console-after-enabling-amdgpu.74153/ > I suspected an issue with the 2560x1440 of my monitor, and indeed: the > problem went away with a 1920x1080 monitor. > > Interestingly, the problem also went away once boot was complete. > Switching to a tty with e.g.: Ctrl+Alt+F1 presented everything in order. > > Does anyone have an idea what could be going on (bug, or some EDID issue > with my monitor?) and more importantly, how to fix it? Just to share my resolution: it turns out I was misconfiguring the module in /etc/modprobe.d/amdgpu.conf. I completely forgot that I even created that file. It was passing the dc=0 parameter to the module, I believe to address some issue I was experiencing with the amdgpu driver years ago.
