Stickies Taskbar icon flickers on Windows 11.

I just got Windows 11 installed. Everything seems fine, but the taskbar is large and difficult to make smaller. I have used the registry tweak to get the icons smaller, but the Stickies icon now flickers.

Which task bar do you mean?  The task bar along the bottom of the screen is a Windows thing, and isn't part of Stickies, so I guess you don't mean that?
