Hi,
I'm having an issue in 3.4.0 where ArcPro is creating weird artifacts in multiple unique Projects. Take a look:


The 2nd image shows that it's creating these artifacts around the basemap as well-- not just the features I'm using.
This issue doesn't exist outside of ArcPro, leading me to think it's not a PC issue, such as a bad graphics card.
No idea what's happening, preventing me from asking intelligent questions.
Thanks for your help!
