Created attachment 185796 [details] journalctl log SUMMARY Clipboard fills with partial selections while selecting text (when “Keep the selection and clipboard the same” is enabled) Unfortunately, I cannot determine the exact Plasma version where this issue was introduced. However, it has been occurring for more than six months and across several Plasma 6.x releases. STEPS TO REPRODUCE 1. Open any text editor or application (e.g. vscode, chromium, 1password...) 2. In Klipper settings, enable “Keep the selection and clipboard the same”. 3. Click and hold the left mouse button, then drag to select text slowly, e.g. This is a test sentence OBSERVED RESULT During the selection process, Klipper/clipboard stores every intermediate selection, such as: EXPECTED RESULT This is a test sentence This is a te This is SOFTWARE/OS VERSIONS Linux/KDE Plasma: 6.17.1-arch1-1 #1 SMP PREEMPT_DYNAMIC Mon, 06 Oct 2025 18:48:29 +0000 x86_64 GNU/Linux KDE Plasma Version: 6.4.5 KDE Frameworks Version: 6.18.0 Qt Version: 5.15.17 Wayland ADDITIONAL INFORMATION Sreenshot is attached.

I can't repro this, for me it waits for the mouse button to be lifted before the selection is done. One thing I find confusing in your report is: Qt Version: 5.15.17 Can you check your system information in plasma settings and copy them from there?
