Bug ID: 503499
Summary: KDE Connect pointer causes fullscreen presentations to
lose focus on Wayland
Classification: Applications
Product: kdeconnect
Version: 25.04.0
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: common
Assignee: albertv...@gmail.com

Target Milestone: ---
**Summary:**
When using KDE Connect's "remote control for presentations" pointer on Plasma
Wayland, activating the pointer window causes fullscreen presentation windows
to lose focus. As a result, the Plasma taskbar becomes visible during
fullscreen presentations, breaking the visual experience. This does not happen
on X11.
**Steps to reproduce:**
1. Login to a Plasma Wayland session.
2. Open any presentation application (e.g., LibreOffice Impress, Okular) in
fullscreen mode.
3. Connect a phone via KDE Connect.
4. Use the "Remote Input" or "Presentation Remote" to activate the pointer.
**Observed behavior:**
- The presentation window loses fullscreen focus.
- The Plasma taskbar becomes visible on top of the presentation.
- Interaction is disrupted, and the presentation looks broken.
**Expected behavior:**
- The presentation window should remain fullscreen and focused.
- The pointer should overlay without stealing window focus or affecting
fullscreen.
**Technical analysis:**
- The pointer window is created with `Qt::WindowDoesNotAcceptFocus` and several
flags like `Qt::Tool`, `Qt::FramelessWindowHint`, etc.
- However, on Wayland, just creating a new top-level window is enough to cause
focus changes.
- Proper Wayland behavior would require using layer-shell protocol (e.g., with
a surface layer like overlay/background) or input-inhibition protocols.
- Simply setting window flags is not enough under Wayland security rules.
**Environment:**
- Plasma 6.3.4 / Wayland session
- KDE Connect version: 25.04
- Qt version: 6.9.0
- Distribution: Fedora Linux
**Possible solution:**
- Create the pointer window using layer-shell protocol (Plasma/KWin supports
this).
- Alternatively, create a pointer surface that doesn't affect the focus stack.
**Additional information:**
- Problem does not occur under X11.
- Using XWayland for KDE Connect does not fix the issue either.
Thanks for the awesome work on KDE Connect!
P.S.: Analysis done with the help of chatgpt!
