When you are viewing a cut scene or going through a conversation in Diablo IV, you may notice some symbols flashing on the screen. To see how you can prevent this weird graphical glitch from occurring, you can take a look at this troubleshooting article from Seeking Tech.
Based on our experience, as well as reports from other players, this bug occurs when you have minions summoned before you entered the cinematic and/or dialogue. You should see the unbreakable chains flash on the screen.
This can occur if you are playing the action role-playing game on the PC, PlayStation 4, PlayStation 5, PlayStation 5 Digital Edition, Xbox One, Xbox One S, Xbox One X, Xbox Series S and Xbox Series X. You can see a video of the glitch occurring below (via Reddit user ChronoMode87):
In order to stop this visual bug, you should dismiss your minions before talking to another person. By doing so, you should no longer see any chain symbols.
Of course, you should also make sure you have the latest patch downloaded for the game. This flashing symbol glitch has been widely reported since the beta tests. Hopefully, the development team will eventually fix this problem.
