SUMMARY
***
NOTE: If you are reporting a crash, please try to attach a backtrace with debug symbols.
See https://community.kde.org/Guidelines_and_HOWTOs/Debugging/How_to_create_useful_crash_reports
***

Multiple entries for the same item are added to the clipboard when highlighting for copy/paste, possibly due to the clipboard copying after every space(?).  Only seems to happen from browser (I use Vivaldi), Konsole highlight+copy/paste works as desired (only one entry).


STEPS TO REPRODUCE
1. Highlight a block of text
2. View clipboard
3. See multiple entries of the same item

OBSERVED RESULT
Multiple entries for an item

EXPECTED RESULT
One entry for the item after releasing mouse for highlight

I can't reproduce the issue by selecting text in Firefox or Kate (both Native Wayland apps) with those settings. Can you screenshot your config window so I can be sure I'm testing it the same way?

Comment 3 Kerr Avon 2024-03-13 08:32:18 UTC

I can replicate the issue on Wayland in both Google Chrome and Chromium, but not in Kate.

Comment 4 Marco Martin 2024-03-13 09:38:44 UTC

what i can kinda replicate, is that when the user is selecting text with the mouse it's pushing in the clipboard history every single string in the process, ie, if i select dragging with the mouse the string "hello", i will have in the history ["hello", "hell", "hel", "he", "h"]

Comment 5 Marco Martin 2024-03-13 09:42:32 UTC

and yes, it seems specific to chromium (and derivatives) only when using native wayland ozone-platform-hint
