Many entries in clipboard dropdown. Each having one letter more than the "older" one.

This is a bug in Chromium, but should be worked around with the fix for Bug 512076. If you're still seeing it, please report it to Chromium. Thanks!

I have 6.5.4, so I wonder.

Reading up a bit on https://wayland.app/protocols/ext-data-control-v1 it looks  like the protocol is designed to offer incremental selection. The consumer though should drop previous offers.
I think this is not a duplicate of 512076. I may have similar symptoms. And I don't see this on a laptop from 2019, but do on one from 2015 and noticed less entries when selecting text "really fast".
