Thanks for the bug report.

However, Plasma 5.27.11 no longer receives updates or maintenance from KDE; active versions are 6.4.5 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need support for Plasma 5.27.11, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

If this issue is still reproducible in Plasma 6.4.5 or later, feel free to re-open this bug report.

Thanks for understanding.

Issue really was/is middle click paste. With mouse used for scrollinng it picked up middle click paste too often.
In 24.04 x11 there is not setting to turn off middle click paste.
But changing to wayland, there is a setting to turn off middle click paste & that seems to resolve issue.

I use middle scroll wheel on mouse a lot, and getting middle click paste.
Others seem to have issue.

(In reply to oldfred from comment #4)
This bug has been closed, since the version of Plasma on your system is no longer maintained by KDE. You'll need to raise any further issues in the Kubuntu bug tracker. Thanks.
