Bug ID: 421039
Summary: Unwanted velocity and bounce effects / option to
disable all animations
Product: okular
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: okular-de...@kde.org
Reporter: nfx...@gmail.com
Target Milestone: ---
SUMMARY
I need an option to disable all animations or related things.
STEPS TO REPRODUCE
- Dragging with the mouse and then releasing makes the viewed document keep
moving until it decelerates to a halt. This is unwanted. The document should
never ever move on its own.
- Doing this with a "high" magnitude makes the document move significantly and
even bounce off the borders. It's like it's some sort of game (pinball?). This
is unwanted. I want to view the document at the point where I stopped dragging,
not somewhere else or even the next page. It's not a game either.
- It allows you to drag the document out of bounds, and moves back when you
release the mouse. This is unwanted. I have to admit this behavior freaks me
out. If I wanted it, I'd use macOS or something.
- When scrolling with the keyboard, it does some sort of soft scrolling effect.
This is unwanted. I want it to scroll instantly, not bother me with a fraction
of second of waiting.
- (This is an old one.) When searching with Edit->Find, it does an animated
scroll to the next page. This is unwanted. It's pointless, makes search take
longer, and if this was intended as eye candy, it doesn't even work, because
rendering is often not fast enough.
OBSERVED RESULT
Forced "slowness", UX annoyance, possibly higher CPU usage (possibly energy
usage and battery depletion if on laptop).
EXPECTED RESULT
Instant, fast UI reaction.
