Bug ID: 449497
Summary: Expose effect does not update when changing virtual
desktops while it's open
Product: kwin
Version: 5.23.4
Platform: Manjaro
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: effects-present-windows
Assignee: kwin-bugs-n...@kde.org
Reporter: kde-b...@nicoweio.33mail.com
Target Milestone: ---
SUMMARY
The Expose effect does not update when changing virtual desktops while it's
open. That is, I see the panel updating in the background and after closing the
Expose effect I can confirm that the virtual desktop was switched as expected.
But before closing, the "exposed" windows still reflected the old – now "wrong"
– virtual desktop.
A note on invocation: If I were to use the regular keyboard shortcuts while the
Expose effect is active, nothing would happen. That's maybe not ideal, but a
fair choice. However, I use Touchegg with the "Switch desktop" preset. I also
verified that calling `qdbus org.kde.kglobalaccel /component/kwin
org.kde.kglobalaccel.Component.invokeShortcut "Switch to Next Desktop"` shows
the same behaviour.
STEPS TO REPRODUCE
1. Have some windows open in (at least) two desktops.
2. Open the Expose effect
3. Switch the virtual desktop, for example by using `sleep 2 && qdbus
org.kde.kglobalaccel /component/kwin
org.kde.kglobalaccel.Component.invokeShortcut "Switch to Next Desktop"` or by
using Touchegg.
OBSERVED RESULT
The virtual desktop changes, but the displayed windows are still the ones from
the virtual desktop where the effect was opened.
EXPECTED RESULT
The shown windows should always reflect the current virtual desktop. An
animation would be cool, but just updating the shown windows would be
sufficient.
