Krunner flickering while typing

SUMMARY
After upgrading from KDE Plasma 5 to Plasma 6, I have observed that Krunner exhibits flickering behavior during typing

STEPS TO REPRODUCE
1. Open Krunner by pressing the designated shortcut (e.g., Alt + Space).
2.  Type various characters that are likely to yield search results, such as document names, application titles, or commands, to observe the changing suggestions.

OBSERVED RESULT
The application flickers when it updates suggestions as you type. See the attached video for more details (flicker.mp4).

EXPECTED RESULT
The application window should not flicker.
