I have installed the lubuntu desktop today from the software center. I was using Unity and it was so slow for some reason. When I open simple screen recorder, the panel got filled with multiple icons of it. The screenshot is attached. This is not happening for any other application. I have tried chrome, brackets, panel settings etc. I have checked the system monitor app to see whether it is opened multiple times or not, but I could see only one entry there.
Could somebody please help?
