Comparison between slide desktop and some other animations
SUMMARY
Since upgrading to 5.25.0 I noticed that the animation speed when switching
desktops with the slide effect (by scrolling on the desktop, the pager on the
panel or via keyboard shortcuts) is significantly slower than before, but I
don't see any other animations being changed that drastically. Increasing the
global animation speed in System Settings does speed it up, however to make it
feel like how it was in 5.24 all other animations end up near instant as a
result.
I have attached a screen recording to show what the slide desktop animation
looks like compared to some other animations (overview, showing the application
launcher, window switching via Alt+Tab, show desktop).
STEPS TO REPRODUCE
1. Enable the slide desktop animation
2. Switch to another virtual desktop using a keyboard shortcut or scrolling on
the desktop or scrolling on the pager
3. Observe the animation speed
OBSERVED RESULT
The animation is much slower than others in Plasma (say opening the application
launcher).
EXPECTED RESULT
The animation speeds should be at least somewhat consistent with the rest of
the system.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 5.25.0
KDE Frameworks Version: 5.95.0
Qt Version: 5.15.4

ADDITIONAL INFORMATION
My touchpad unfortunately only supports two fingers, and I also don't have a
touchscreen, so the one to one animation thing doesn't help in my case. My
mouse wheel doesn't have high precision or anything like that either, it's just
a Logitech M90, which is like the cheapest mouse I found in the store I bought
it from.
