Just had a video meeting with some people in another office and their meeting room has a wallpaper (or some other kind of print) that is just a ton of lines intersecting at random angles. Unsurprisingly, video encoders don't really like this and it means that the background of the call ends up being full of noise and artifacting. What an incredible choice for a room that is used almost exclusively for video calls. Like making the set of a newsroom out of a pattern that would cause a moiré effect
