Jaspersoft Studio 6.16.0 on macOS Big Sur seems to be broken

I have installed the latest version of Jaspersoft Studio on my macOS.

Now, I have created a sample project to create a jasper report for learning.

The issues that I have noticed are given below :

1. Report templates are not updating as soon as I added some elements.

2. Drag and drop to added elements is not updating itself. I need to do random scrolling outside the template to update it.

3. Selection of an element is also not happening directly. Random Scrolling need to be done for that as well and so on..

Is there any issues of latest Jaspersoft Studio with macOS Big Sur ?

This is a known issue of Jaspersoft Studio which has already been fixed:

[#13296] - The Jaspersoft Studio in the macOS Big Sur version is broken (does not repaint screen)

See comment #22 and #37 for patches.
