Yes! The artifacts reappear when I hit Shift-Alt-F12. Good catch!

Title:
delayed display update / konsole artifacts
Status in xorg package in Ubuntu:
Confirmed
Bug description:
Since one of the recent Impish updates, konsole shows artifacts and
reacts slowly. In fact, it looks like screen updates are pipelined on
pixel-group granularity somehow, and the pipeline isn't drained
completely: When more text goes to the terminal (e.g., I type
something), existing artifacts vanish, but new ones (in the new text)
appear.
Unfortunately, I don't see any of the previous konsole .deb releases
(e.g. 4:21.08.1-1 or 4:21.08.0-1) on the Ubuntu mirrors, so I cannot
go back and simply check whether the newest konsole updates are the
culprit. I'm actually not sure whether konsole is responsible at all,
I originally intended to file against xorg; however, I see those
artifacts in neither xterm nor gnome-terminal.
Find attached a screenshot (taken with an external camera; these
artifacts cannot be recorded using a screenshot tool such as
imagemagick's "import") where I ran "ls" in /tmp, and cleared the
terminal with ^L afterwards. The screen is still littered with
remains of the "ls" output. It took a few tries to get artifacts this
pronounced, though; usually they only concern small parts of the
terminal.
