So I've been trying to identify this issue for months and I still cannot for the life of me figure this out. I've checked EVERYTHING, and I still can't trace where the lag is coming from. Reinstalled Windows multiple times and still experience the lag.

According to Process Hacker, SHCore.dll!GetDpiForMonitor+0x70 is constantly being called in the threads. Extremely apparent when the slowdown happens. I do have a short trace ETL that I can upload but it may take a while. How could I try to identify the issue myself using WPA?
