I have a 720p webcam (Logitech C270) that has worked fine on macOS for years. However, it's displaying really low resolution (240p?) in both Zoom and VLC on Ubuntu 22.04.

Choppy edges when capturing in VLC:

In zoom config I've tried turning off autoscale and other commonly reported settings
In vlc i've tried manually entering 1280x720 dimensions and the framerate says 60
youtube videos display just fine, so i don't think it's a video card issue

Trying to switch to Linux as my daily driver <3

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
