The black flickering is still a problem. AMD customer support notices that if it is a problem that only occurs on one game, they demand the developer to fix it.
You blocked my workaround with DXVK with your anti-cheat as reported in EA Javelin Anti Cheat crashes with DXVK | EA Forums - 13582778 so there is now nothing I can do. :(
Please fix both the crash and the visual glitch.
