I get the same sort of behavior when I use Meta+L to "Quick Tile to Left" with
either Firefox 101.0.1 or Chromium 103.0.5060.53 in KDE Neon 5.25.

If I drag the title bar to the left to tile to the left, I do not see this
behavior.

See the attached gif. In it, I start with Firefox maximized, then press Meta+L
to tile to the left to exhibit the flicker. Then I Meta+Up to maximize again,
then I drag the window to the left to tile without flicker, then I maximize
with the title bar Maximize button.
