Overprint Preview unbearably slow

When using overprint preview this app grinds to a halt, it's absolutely awful, please fix / improve

Mac OS 0.15.6,
iMac (Retina 5K, 27-inch, 2019)
3.7 GHz 6-Core Intel Core i5
64 GB 2667 MHz DDR4
Radeon Pro 580X 8 GB

Ai 24.2.3

switching between overprint preview brings my Mac to a slow grind
My expected result... that a professional application is fit for purpose
My actual result.... a slow and un-usable not fit for purchase application that I have no choice other than to use.!!!

    I have the same problem, ever since I started using my iMac 5K 2019.

    - Switching to Overprint Preview or Pixel Preview.
    - Scrolling the screen and "Hand tool" is slowing down.
    - It also happens with newly created empty documents.
    - Artboards and guides are grayed out.

    Workaround
    - Make the window smaller.

    -------------------------

    私もiMac 5K 2019を使うようになってからずっと同じトラブルを抱えています。

    - オーバープリントプレビューまたはピクセルプレビューに切り替える
    - 画面のスクロールや「Hand tool」の操作が遅くなる
    - 新規作成した空のドキュメントでも発生する
    - アートボードやガイドの表示もグレーアウトしておかしくなる

    回避策
    - ウインドウを小さくする

    Overprint preview forces Ai to turn off GPU preview.
    Usually it’s not that a great difference (maybe it’s because I am used to CPU while GPU still feels faster)... i5 is a quite fast thing... It might be a document that you are editing.
    Do all you documents behave the same way?
