Focal: graphics extremely choppy — but not on the login screen

I've been having problems with my dell Optiplex, which runs 18.04 and has a built-in, integrated Intel GPU. I tried putting an AMD Radeon external video card in it, but this didn't seem to improve my video enough so I removed it. Now, my video is very choppy and I've tried rolling back the kernel, creating a new user, and switching between X and Wayland.

However, there is one place where my video is very smooth and this is on the login screen. If I enable the onscreen keyboard, and focus on the login field, the keyboard will pop up in a way that's prompt, fluid, and responsive, as though there's nothing wrong with my video at all.

Therefore, there's something about the X (and Wayland) environment that isn't rendering video properly.

In my experience with `AMD Radeon RX 580` , open source driver provided by Ubuntu was not good enough and caused very slow motion. Try installing the native Radeon drivers from here: https://www.amd.com/en/support

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.
