SUMMARY When hovering over an icon, the preview area will take up the entire screen with the actual preview centered in the popup window. This will happen whether the option, "Show small window previews when hovering over tasks" is checked or not. Additionally (possibly a separate bug) hovering over other elements of the panel will cause the screen to flash repeatedly for example hovering over the Application Menu. STEPS TO REPRODUCE 1. Add the Icons-Only Task Manager to your panel. 2. Hover over different open windows. OBSERVED RESULT A preview area covering the entire screen appears with either a small preview or no preview if the "Show small window previews when hovering over tasks" option is disabled. EXPECTED RESULT A small popup over the hovered icon.
