Bug ID: 490440
Summary: Animated cursor freezes while stationary
Classification: Plasma
Product: plasmashell
Version: 6.1.2
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: perso...@quenten.nl
CC: k...@davidedmundson.co.uk
Target Milestone: 1.0
SUMMARY
I use an animated cursor on my machine. Since a recent update (I think I went
from 6.0 to 6.1) my animated cursor has been freezing up while the cursor is
stationary. Sometimes it does progress through the animation a bit, even
skipping some frames occasionally or sporadically glitching.
Before this happened, my cursor constantly moved around and was animated, but
now it's not anymore. It's as if there is some sort of optimization that was
introduced that broke this, but I don't know.
STEPS TO REPRODUCE
1. In KDE Plasma settings, navigate to "Appearance & Style" -> "Colors &
Themes" -> "Cursors".
2. Click "Install from File..." and select the tar.gz file I attached
(Hina.tar.gz) to install the cursor. This is the animated cursor I use.
3. Select the cursor and press "Apply" to apply the cursor to your desktop.
4. Place the cursor on a flat UI object, like a background. This makes sure the
cursor is the "default"/"left_ptr" state. The cursor has different versions
(and animations) depending on the type of cursor (pointer, dragging, help,
resize, etc). This bug happens on all variants, but it's easiest to see on the
default one.
5. Observe the cursor while not moving the mouse. The animation is frozen (she
is supposed to spin around in circles) while the mouse is stationary.
6. Continuously move the cursor around on the screen and observe. You should
see that Hina is spinning and spinning in an animation. (Moving the cursor
slowly makes it easier to see)
7. Stop moving again and observe the cursor animation stopping again.
OBSERVED RESULT
While the mouse is not moved, the animation is frozen. When moving the mouse,
the animation is not frozen.
EXPECTED RESULT
The cursor animation should always be running and never stop or freeze.
SOFTWARE/OS VERSIONS
