When opening the ActivityManager, the following error is logged once per activity: file:///usr/share/plasma/shells/org.kde.plasma.desktop/contents/activitymanager/ActivityItem.qml:77: ReferenceError: size is not defined For reference: http://doc.qt.io/qt-5/qml-qtquick-image.html#sourceSize-prop None of the activities shows a background thumbnail here - I wonder whether this is related?
It is a bug, but I don't think it's causing your lack of thumbnail, the code for the image providers handles the case of there being no source size and returns something arbitrary (which is the correct behaviour in that case)
the lack of thumbnail should be adressed at the latest thumbnail generation refactor, this is a separate issue.

Image has width and height properties, not "size" Summary: this makes it actually do what it was intended to, set the source size to the actual thumbnail size to keep a scaled down texture in menory Test Plan: normal usage, seems to work as expected, no warning Reviewers: #plasma, sebas, davidedmundson Reviewed By: #plasma, sebas, davidedmundson Subscribers: davidedmundson, broulik, apol, plasma-devel Tags: #plasma Differential Revision: https://phabricator.kde.org/D2919 M +1 -1 desktoppackage/contents/activitymanager/ActivityItem.qml http://commits.kde.org/plasma-desktop/7cbcf46b332ef9c22306c5a628444cd81d0222b5
