Video example of swapping activities

SUMMARY
When changing activities, and the wallpaper is visible, the wallpaper scrolls from black to the set wallpaper instead of switching between the two activity's selected wallpapers.

STEPS TO REPRODUCE
1. Set up numerous activities
2. Set different wallpapers on each activity (probably still noticeable with the same wallpaper to be fair)
3. Switch between activities

OBSERVED RESULT
Wallpaper changes to black then slides to set wallpaper

EXPECTED RESULT
Either it should instantly swap to the newly selected activity's wallpaper or it should transition smoothly between the two without a black interim screen.

SOFTWARE/OS VERSIONS
KDE Plasma Version: 5.24.4
KDE Frameworks Version: 5.92.0
Qt Version: 5.15.3
Graphics Platform: Wayland

ADDITIONAL INFORMATION
The Component Description of "Activity Switcher" states:
"The panel on the left where one can switch activities. All other activity related things should be in kactivities."
But I do not see a kactivities (or similar) Component in the list, so I apologise if this is filed incorrectly.
