Visual bugs since latest patch

I have been having in game choppy issues on specific maps. The issue is difficult to describe. When I travel down a certain lane, my hero, minions, enemy heroes disappear from the screen in a vertical direction and then jump back into frame. There are very specific areas on the map this happens. This happens on the bottom lane every time on the pirate map. I do not think that it ever happens on the tribute map or the seeds map. I thought it was a patch issue and thought it would improve with later patches. I have troubleshooted this issue a lot on my own and it is not an ISP issue, display issue, or an in game graphics issue. I have gone down to the lowest setting, and it still occurs. This only happens on HOTS. Any advice would be great.
I have a Macbook Pro Retina display, 2.2GHz Quad-Core Intel i7, 16GB 1600 MHz RAM, Intel Iris Pro 1536MB Graphics Card. Mid 2015 model. This issue did not start happening until around October 2019.

Thank you
