There are some other issues that may be simply unfixable:

On macOS Ventura and newer, Stage Manager is completely unavailable. Along with showing the Desktop using the trackpad gesture. The best work-around for this is to simply downgrade to macOS Monterey.

Some screen savers don't work at all. In fact, they just show a black screen. "Drift," "Monterey," "Ventura" are examples of screen savers that don't work.

Note here, the aerial screen saver on macOS Sonoma and Sequoia somehow works; but it's not pretty. You may also notice that the screen saver that has worked since the iMac G3 age called "Flurry" doesn't work very well on macOS Ventura or newer. The screen saver engine changed, and therefore requires much more energy to run.

Some blurs may remain broken; even when you've checked "Beta Blur" inside of OpenCore. There are some blurs (like notifications) that will still remain broken.

You may also notice that absolutely no blur will work on macOS Ventura and newer. I personally have had no issues with the blurs while running macOS Big Sur only.
