For the loading animations problem(feels broken), I think I have found a solution. Well, I would not call it a solution, just a tweak. First of all, this cursor is my go to cursor. In every pc & in every laptop I use this.
So, again thanks to the developer for such a nice cursor set and it's continuous updates.
Because of this animation problem, for a couple of days, I was using the 3.1 version, also the 4.0 version.
Then, I combined(some cursor from 3.1, some from 4.0 & 4.1) all those together in the windows cursor settings (settings>personalize>themes>mouse cursor).
By doing that, it has appeared that every time I select 4.1 version's animated "Normal Select" cursor, all the animations start flickering & feel broken.
How to fix it:
1. Install the 4.1 version
2. in windows cursor settings, select the "Normal Select" from the static folder.(So no animation on "Normal Select")
3. leave everything as it is
My cursor now working just fine.
I hope it will work with everyone.
