Bug Description
I upgraded to Kubuntu 21.04 from 20.10 two days ago. Since then, whenever I do something (type or use mouse/touchpad) I have 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 (it seems that is mostly until the next input event, so for example often I have to wiggle the mouse), 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 very 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 chose the plasmashell app, since ubuntu-bug more or less requires an application/
I am on a Dell Precision 5530, with Intel graphics enabled.

An additional observation - something that makes writing code in vim-style environments even more aggravating. It appears that only events accepted by the current application (e.g. vim in a console window) can get the visuals back to what they should be. And since vim don't generally do anything about wiggle-mouse type of events, I have to do something with the keyboard, which in vim often will mean doing something disruptive to what I'm actually trying to do. Say I'm searching for a symbol that I want to do something with - I find it, but the visuals immediately reverts back to where I was. I can use one of the movement commands, which will then get me back in the right vicinity, but no longer at the characther where I planned to do something.
Additional info - currently running Intel graphics, although nvidia exists via the Prime stuff. I don't normally bother to deal with it since I mostly do programming work that don't involve heavy graphics.
