Bug ID: 455767
Summary: Transition into and out of new Window Management
desktop effects is jagged
Product: kwin
Version: unspecified
Platform: Archlinux Packages
OS: Linux
Status: REPORTED
Keywords: regression
Severity: normal
Priority: NOR
Component: effects-window-management
Assignee: kwin-bugs-n...@kde.org
Reporter: hugh.ga...@tutamail.com
Target Milestone: ---
SUMMARY
The Desktop Grid and Present Windows desktop effects are kwin tools I use a
lot. After years of use they are ingrained into my workflow.
The transition into and out of these Window Management desktop effects prior to
5.25 was smooth as butter. It looked like some sort of zoom animation was used
to transition to and from the active desktop to each specfic desktop effect.
Both the speed and smoothness of this transition animation was great. It was
easy on the eye.
With the redevelopment of these Window Management desktop effects in 5.25 the
transitions into and out of them are now rough, jagged and anything but smooth.
Overview desktop effect has this issue also.
They are jagged and rough enough to give me a headache after about 45 minutes
of use. Desktop grid seems to be the worst of the group. It is more jagged
than the others.
I use between 4 and 8 virtual desktops usually and have anywhere from 4-12
applications open at any one time, on average.
A restored 5.24.5 system I tested with 2-8 virtual desktops and 16 open
applications was smooth transitioning in and out.
My current 5.25.1 system I tested with 2-4 virtual desktops and 4 open
applications was very jagged transitioning in and out. Reducing the number of
deskops and applications didn't improve smoothness.
Hopefully the cause of this regression can be found and a fix developed.
Headaches kinda suck.
STEPS TO REPRODUCE
>From an active desktop open a Window Management desktop effect (desktop grid,
present window or overview).
OBSERVED RESULT
Transition animation into the desktop effect is jagged, rough, jerky and not
smooth. Particularly the desktop grid.
EXPECTED RESULT
Transition animation into the desktop effect should be smooth, like it was in
5.24.5.
