I did all 3 updates from different tabs in the same konsole (KDE), so the terminal is VT100 compatible. It really looked like there was a bad ANSI escape somewhere. It was night/day different than the last time I updated and I've probably update each of these boxes of 1000 times during the past 10 years or so.
My guess would be that the old (KDE Trinity) version of konsole that you're using doesn't support some modern feature of terminals.

No, that's not it either, I have used ALL ANSI escapes (and tput, etc..) in the terminals without issue. The key here seems to relate to the "Total" line triggering a new line part way through the package download. The faster the host, the less noticeable the jitter. This is from the newer box that I though was NOT affected: linux-docs-5.12.9.arch1-1-x86_64 Total (0/4) 0.0 B 0.00 B/s 00:00 [--------------------------------------] 0% linux-lts-5.10.42-1-x86_64x86_64 22.0 MiB 5.75 MiB/s 00:04 [######################################] 100% Total (1/4) 20.9 MiB 6.08 MiB/s 00:17 [######--------------------------------] 16% linux-lts-headers-5.10.42-1-x86_64 74.3 MiB 5.85 MiB/s 00:13 [######################################] 100% Total (2/4) 95.5 MiB 6.08 MiB/s 00:05 [############################----------] 74% nodejs-16.3.0-1-x86_64.42-1-x86_64 22.7 MiB 5.57 MiB/s 00:04 [######################################] 100% Total (3/4) 117.8 MiB 6.06 MiB/s 00:01 [##################################----] 92% Total (4/4) 127.8 MiB 5.73 MiB/s 00:22 [######################################] 100% It was affected, it just wasn't as noticeable when pacman was running because the screen refresh was fast. Also note, I do all updates over SSH (and Wifi) to headless boxes, so there many be some network delay contributing as well. But the point being, for 12 years I have never seen anything like this issue, and now, it is quite notable. -- David C. Rankin, J.D.,P.E.
