https://invent.kde.org/plasma/plasma-desktop/-/merge_requests/2565 is already merged to plasma 6.2. but i still having this issue on plasma 6.4. are you sure that they are the same bug?

The merge request you found unfortunately didn't fully fix the issue, and we discovered that it's an upstream issue, not something we can fix ourselves.
