World Map/UI lag issue (10/15 FPS)

note for possible merge:

FPS locked to 10 in menu 1.13.16.0

My sim sometimes drops to 10 fps locked in the menu (and sometimes in flight). Anyone seen this happen too? My system: i9 9900k rtx 3090 32gb 3200mhz [2021-02-19 01_05_48-Microsoft Flight Simulator - 1.13.16.0]
