Bug ID: 480313
Summary: The window preview shown when hovering over tasks is
broken on Plasma Wayland 6.0
Classification: Plasma
Product: plasmashell
Version: 5.92.0
Platform: Arch Linux
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Task Manager and Icons-Only Task Manager
Assignee: plasma-b...@kde.org

Hovering over a single task
SUMMARY
Title.
STEPS TO REPRODUCE
1. Configure Icons-only Task Manager to show small window previews when
hovering over tasks
2. Launch an application, a task shows up in the panel now
3. Hover over this task and see that there is no window preview
4. (If you launched multiple instances of the same application) hover over the
task and see a messed up preview
OBSERVED RESULT
When I am hovering over a task, the window preview shows only the window title,
its description, and optionally the media controls.
When I am hovering over a group of tasks, the window preview is completely
broken including layout.
Furthermore, each time I hover a task, plasmashell logs this message in the
system journal: `error creating screencast "Could not find window id 0"`.
EXPECTED RESULT
Being able to see the window preview.
SOFTWARE/OS VERSIONS
Operating System: Arch Linux
KDE Plasma Version: 6.0 RC1
KDE Frameworks Version: 5.249.0
Qt Version: 6.7.0
Kernel Version: 6.7.0-arch3-1 (64-bit)
Graphics Platform: Wayland
ADDITIONAL INFORMATION
The behaviour seems to be reliably triggerable when I put the computer to sleep
and wake it up.
I should note that I am running on a beta release of Qt.
