Description Miroslav Spehar 2018-07-08 17:06:21 UTC

on every mouseover event for icons pinned in icons only task manager, error is reported in system journal:

plasmashell[1327]: file:///usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/Task.qml:342: Unable to assign [undefined] to int

reproducible: always

Is this still an issue with [1], given you're on 5.13.2 which should have this fix.

Comment 2 Serhiy Zahoriya 2019-02-10 00:39:27 UTC

Getting this error on 5.14.90 on Ubuntu 19.04.

Additionally, every time a launched icon is hovered message changes to

> qt.qpa.xcb: QXcbConnection: XCB error: 2 (BadValue), sequence: 19784, resource id: 56623121, major code: 142 (Unknown), minor code: 3

Comment 3 Serhiy Zahoriya 2019-02-10 00:43:59 UTC

And 

/usr/share/plasma/plasmoids/org.kde.plasma.taskmanager/contents/ui/ToolTipInstance.qml:437: ReferenceError: VirtualDesktop is not defined

if there are multiple windows for icon being hovered

Comment 4 Serhiy Zahoriya 2019-02-10 01:13:10 UTC

Is this workaround/fix ok?

return model.AppPid ? model.AppPid : 0;

Comment 5 Serhiy Zahoriya 2019-02-10 13:20:28 UTC

XCB error does not appear if tooltips on hover are enabled and the tooltip is already shown.

Please confirm if this patch will work or not

Comment 7 Eike Hein 2019-02-11 18:00:58 UTC

The VirtualDesktop changes are no longer required, Plasma 5.15 has Virtual Desktops on Wayland. The rest you can upload to Phabricator.

Comment 8 Christoph Feck 2019-03-09 15:47:58 UTC

Serhiy, more information for uploading the patch to https://phabricator.kde.org/differential/diff/create/ is available at https://community.kde.org/Infrastructure/Phabricator

Not Wayland-specific and also fixed now. :)
