I connect my laptop to a FH additional monitor, got have problem with it.
I was connected the monitor ~2 months ago also there wasn’t a problem on that time and then I connect 2-3 weeks ago there was a glitch issue with the same config.
I tried with a fedora usb stick. I boot same hardware system with it for ensuring any hardware issue. It worked very well.
I got a video about it but i think reporting issue is enough for now. If you need whole video I can share it.
