SUMMARY

STEPS TO REPRODUCE
1. Disable animations (in kdeglobals: [KDE] AnimationDurationFactor=0.0)
2. Open Dolphin
3. Toggle "Show All Entries" in places panel

Applications can query the QStyle::SH_Widget_Animation_Duration stylehint.

OBSERVED RESULT
New entries are faded in

EXPECTED RESULT
They are just there, no fading

SOFTWARE/OS VERSIONS
git master
Comment 1 Nate Graham 2022-01-20 22:45:14 UTC 
Confirmed.

We should just remove the animation entirely as we have generally concluded that hover fade animations for items list and grid views are weird and make the system feel laggy.
Comment 2 Ahmad Samir 2022-04-19 12:43:22 UTC 
I think this isn't related to hover effects, it looks like this animation happens when you select "Show all entries",

Pushed by ahmadsamir into branch 'master'.

KFilePlacesView: use animations only if QStyle::SH_Widget_Animation_Duration > 0

This affects the "Show all Entries" and the icon size change actions.
FIXED-IN: 5.94
