Bug ID: 502940
Summary: After update to kwin_wayland 6.3.4,
workspace.stackingOrder contains references to
nonexistent windows
Classification: Plasma
Product: kwin
Version: 6.3.4
Platform: openSUSE
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: scripting
Assignee: [email protected]
Reporter: [email protected]
Target Milestone: ---
Since the update to kwin_wayland 6.3.4, workspace.stackingOrder contains
references to windows that have been closed.
This breaks some scripts that rely on workspace.stackingOrder for information
about window stacking.
The issue was discovered using the following script:
const windowStack = [];
for (let i = 0; i < workspace.stackingOrder.length; i++) {
let w = workspace.stackingOrder[i];
if (w.resourceClass == 'plasmashell' || w.resourceClass ==
'xwaylandvideobridge' ||) {
continue;
}
windowStack.push(w);
}
for (let i = 0; i < windowStack.length; i++) {
print(windowStack[i].resourceClass);
}
Viewing the output of the script using journalctl (journalctl -f QT_CATEGORY=js
QT_CATEGORY=kwin_scripting), I can see that there are some references to
windows that have since been closed.
