MultiProgress bar flickering #708
Description
I built a program to download builds artifact from Azure dev-ops. You can see it in bug #669. I use a MultiProgress bar with around 27 progress bars on it. It could be more, it could be less.
Each progress bar is used inside tokio runtime. One per artifact to download. Typically, The rendering is perfect, but I can see flickering on the progress refresh. It is worst on Windows than Linux.
I tried set_move_cursor, different draw target, nothing seams to make a difference. The Python version of the same tool that uses tqdm has no flickering at on any platform.
Issue seams very similar to #226. Any hints I can look at to improve the rendering?
