Ive noticed on the current build, the priorities window is now very glitchy, I have not seen this before. The duplicant faces jump to different images.
I dont think this is a GPU or graphics only bug, as the skill level indicator and the tool tips for skill change randomly, you can see in the video Maries attacking skill go from white to purple to white again.
Load the save game
Open the priorites window, the game must not be paused
