SUMMARY
Maximization effect doesn't work for some windows even though I slowed the effect down. The affected windows are native Wayland applications while for
XWayland applications maximize effect works perfectly.

I tried native wayland apps such as systemsettings5, smplayer, qtcreator, weston-terminal and apps that use XWayland like firefox, gimp, glxgears. The maximize effect doesn't work for wayland native apps while it perfectly works apps run through XWayland.

OBSERVED RESULT
Maximizing native wayland windows happen immediately without showing any effects.

EXPECTED RESULT
Maximizing native wayland windows renders maximization effect.
