Me (and many other people) experience eye-ache from new Macbooks (and windows machines).
I have spent two years of trial-and-error and found that installing macOS Mavericks on my MacBook (pro 13 late 2013, Intel Iris 1536 MB) resolves the issue of eye ache completely. (it is believed that newer systems use harsher version of temporal dithering that causes of a certain group of indivisuals eye aches).
I cannot stay at Mavericks because of software support and security issues, so the only thing is an issue now:
How can I take drivers from Mavericks and install them on Catalina? (I tried replacing .kext in /System/Library/Extensions with old files but it didn't work).

I am having issues with VoodooInput. It loads fine, no errors or KPs, but movement is erratic. It seems when I am moving the cursor with my index finger and then try to click with my thumb, the cursor will shoot to the bottom of the screen, causing erroneous clicks and a lot of headaches. Sometimes it shoots to the top instead. Sometimes it performs as expected. It's unpredictable.
I have used VoodooI2C + VoodooI2CHID instead, and they work perfectly fine, but unfortunately they cause KPs. Plus, I like that VoodooInput is a singular kext. This is why I am trying to see if there's any way to fix this issue.
