Very blurry font rendering in Ubuntu 21.04

mx flag

Here is a screenshot from my terminal:

enter image description here

Black on yellow is fine. Yellow on dark is a little bad and black on red is absolutely terrible. I am using a 4k screen, 60Hz, 100% scaling. Font is Ubuntu Mono.

What causes this and how can I fix it?

I don't see any problem in your screenshot. Does your screen look different? Are you sure you are using the screen's native resolution?

I can see a little blur compared to the surrounding text in your question. But it is difficult to tell if it is caused at your screen or because of fractional scaling when displaying/zooming the image when rendered by AskUbuntu or by my Firefox. Anyway, like @Nmath, I suggest that you check carefully, that you use the screen's native resolution (and 100 % scaling). -- But if you notice differences in blur depending on the colours, I think you should blame the hardware in the screen or your eyes, and not Ubuntu or the graphics driver.

Indeed, I am looking at the screenshot on another computer now and it looks fine. Must be an issue very late in the pipeline to the screen.

Screenshot only looks bad on the affected computer. May be a hardware issue.

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.
