When playing Half Life 2 or Black Mesa and I press the middle button to zoom in, it causes a graphical glitch where there’s a vertical rectangular area in the middle of the screen where some of the textures outside that rectangular area will just disappear until I either turn the flashlight off or zoom back out again.
I did not always have this problem and I am using the same hardware as before and have not made any changes to my in-game graphics settings. I tried the newest drivers for my Geforce 1060 but it did not work. I am using Windows 10 and an oculus rift.
