Whenever you try to capture a video of your screen while playing, be it through a third-party application or the native features of your device, you could encounter some graphical glitches such as the screen blinking, textures or other decorative elements disappearing or a white veil appearing on-top or behind the game.
Those issues manifest only while capturing the screen and are most often triggered by visiting Conjunctivius. Once triggered, these issues can manifest anywhere in game until you either restart the game or stop the capture.
You can find below a few videos showing examples of these glitches.
