If we place Task Manager or Icons Only Task Manager (they probably share some code) on a panel and start moving panel to different screen adges, than Task Manager starts to have problems with rendering its items. - if we move to left screen edge, than its items loose spacing - if we move to different edge (top on video) than Icons Only Task Manager have horizontal spaces but Task Manager doesn't - if we move panel again (right screen edge on video), spaces are lost again and Tasks Managers items have also different width (different margins from panel edges). If we start hovering itmes with mouse cursor than horizontal spaces starts to render and items width starts to fix itslef Please watch video for detailed overview of the issue. Reproducible: Always Steps to Reproduce: 1. Put Icons Only Task Manager or Task Manager on pael 2. Start moving panel to different screen edges 3. Observ problems with Task Manager items rendering Actual Results: Task Manager / Icons Only Task Manager does not render its items the same way when panel is moved across desktop. Expected Results: Task Manager / Icons Only Task Manager should always render its items the same way - no matter where panel is placed/moved.
Also: as you can see on the video, the items contour isn't updated as it should when Task Manager chnages position.
This is due to not using the latest versions of plasma-framework and plasma-desktop together; updates will fix it.
