After input events, graphics show older version for a short while, creating a jumping effect in 21.04

Yesterday I upgraded to Kubuntu 21.04 from 20.10. Since then I have had this issue where the visuals I see seems to revert to an earlier (cached?) state for a very short while. E.g. (just observed on the previous line) I am writing wherever (console, here, ...), and after having written a word or new character, I for a short while (maybe half a second), I see the state a very short while ago, e.g. before I wrote the last two letters, then gets back to actual state. This creates a rather annoying jumping effect. I have also seen it in mouse driven operations, e.g. closing an image in Twitter via the X the image disappearing, coming back, then finally properly disappearing, or sorting lists by clicking sort indicators at the top reverting sorting for a short while.

I am on a Dell Precision 5530, with Intel graphics enabled.

I am not able to google any similar experiences.

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.
