That's what brought me here. Are you running Helium App, just curious if it's the source. I do a lot of work in terminal and my screens either disappear for a second and come back or flicker. In Safari the border content disappears for a second and back again.
My other issue is the trackpad becomes non-responsive for up to 15 seconds, most noticeable in Safari.
This is not a hardware because when I boot from an external SSD (Catalina) it runs like a charm with no issues.
Here are my specs if anyone is curious
MacBook Pro (15-inch, 2018)
Processor 2.6 GHz 6-Core Intel Core i7
Memory 32 GB 2400 MHz DDR4
Graphics Intel UHD Graphics 630 1536 MB
