Bug ID: 470265
Summary: Changing mouse cursor theme does not apply in some
contexts
Classification: Plasma
Product: kwin
Version: 5.24.7
Platform: Kubuntu
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: kwin-bugs-n...@kde.org
Reporter: andy...@mail.ru
Target Milestone: ---
SUMMARY
After changing mouse cursor theme in System Settings, the new cursor theme does
not apply in some contexts, meaning when the mouse cursor is over some parts of
the desktop, the cursor appears as if old theme is in effect. This includes
both the content that was on the screen before the theme was changed (meaning,
for some content the change is applied and of other content it is not), and the
content from applications that are launched after the change was made.
STEPS TO REPRODUCE
1. Go to System Settings -> Appearance -> Cursors and change the current cursor
theme. For example, from Breeze Light to Breeze. Press Apply.
2. Move the mouse to hover over different parts of the screen:
- Desktop (the wallpaper).
- Plasma panel containing task bar, icons, launcher, panel spacer and other
widgets.
- KDE and Qt-based applications, in particular their decoration and the
window contents. For example, System Settings, Muon, KCalc, Yakuake, Konsole,
QtCreator.
- GTK-based applications. For example, Firefox, Meld, GIMP.
- Wine-based applications, e.g. ImgBurn.
- Steam (native Linux client).
3. Launch various applications (Qt and GTK-based) and hover the mouse over
them.
OBSERVED RESULT
The new mouse cursor theme is applied for:
- Most of the Plasma panel widgets, such as icons, task bar, launcher, clock,
KRunner.
- When the panel is in Edit Mode (Right Click on the panel, Enter Edit Mode) -
over the panel or the widget that allows to drag or resize the panel.
- When adding new widgets to the panel - over the window listing widgets.
- After Right Clicking on the panel - over the panel and the context menu.
- Window decorations, regardless of the application (KDE/Qt-based or
GTK-based).
- Yakuake window contents (the console). Yakuake was running prior to the theme
change.
- All GTK-based applications, regardless when they were launched.
The cursor theme is not applied (old cursors are displayed):
- Most KDE and Qt-based applications, except Yakuake. In my test, Konsole was
launched after the theme change and was showing old cursors. Note that Konsole
is unlike Yakuake, although both are showing console content and (I think) use
the same base KDE component for it.
- Plasma panel spacer and the panel itself - the short gaps between icons and
the launcher are showing old mouse cursors. Note that this changes to new
cursors if you Right Click on the panel, as described above.
- Desktop (the wallpaper area).
- Steam and Wine-based applications.
Note that GTK apps are the most consistent - the new theme is applied for all
apps that I tried.
KDE is overall inconsistent. Some Plasma parts use the new cursor theme and
others do not.
EXPECTED RESULT
New cursor theme should consistently apply in all contexts.
