Windows client - graphics issue playing videos

- Windows 10

- Aloha Browser 4.0.05

Playing videos, on any website I've tested so far, produces weird flashing behavior from the video player, especially bad when I move the cursor around and over the video player. I can only describe it as flashing between black screen and the video as well as some sort of color shifting and black screen. If I leave the cursor stationary away from the video player, it only does these quick black-screen -> video flashes every 5 seconds or so.

No idea what this or why it's happening.
