Flickering enemies and weapons

[fotisandstuff]

Hello! Dhewm3 is mostly working fine for me, except that there are times where an enemy may start flashing/flickering, so they become invisible for a few frames. At one point (in that room with the hanging body where you hear a voice that says "help me"), my character's weapon disappeared and his arm went to a default stretched-finger pose for just one second. I tried enabling VSync but the problem persists.

I use the Steam edition of Doom 3 on Windows 10. I use an Acer Aspire E1-570G laptop.
