Feedback Horrible interruptions of my workflow with all sorts of "repaints".

Almost everything triggers a repaint of everything, and under certain circumstances the "repaint" crashes.

Never have I ever seen this in Unity, or any software for that matter and that on a i7, 32GB RAM machine with 8GB GPU in a scene that only features geometry... There are no animations, no scripts no nothing.
Only static elements. 2020 is probably the worst version of Unity ever. Compared to 2020.x even 2019.x seems fluid and simply marvelous. 2020.2.1f1 was bad, 2f1 is worse!

To the Editor "Optimization Team", please STOP optimizing...
the more you claim you optimize the worse it gets.


Here a repaint happened just for opening the build dialog...
others happen just for right clicking on the hierarchy view...

The editor has become so slow that we can even observe the button clicking background process... in slow motion while it crashes.
