Created attachment 120839 [details] Video recording of the bug SUMMARY When kickoff is on vertical panel tabs are dislocated and the first one is not quite visible. Once a tab is changed they're getting located properly everything is fine for the lifetime of plasmashell (i.e. ideally until logout). STEPS TO REPRODUCE 1. Add panel and pace it on left/right screen edge in order to make it vertical. 2. Add "Application Launcher" (kickoff) on it. 3. Open the application launcher 4. Change tabs 5. Close the launcher and open it again. OBSERVED RESULT Tabs are dislocated until first change. See the attached file (also available on: https://giant.gfycat.com/RepulsiveImmaterialJay.webm).
