Hi @Asterias_9,
Let's take a look and see if we can figure out what might be causing this. First, have you had the chance to try repairing the game to see if that helps?
If you're playing through Origin you can right-click on Apex Legends in your Library and click the Repair option when the menu pops up. If you're using Steam try verifying the integrity of the game files to see if that helps. You can find more details on how to verify the files over at the Steam Support website.
Once you've had the chance to give this a shot please let me know if you're still getting any visual issues. Thanks!
