hey so I'm having an issue where there is screen flickering and the protagonist is completely invisible. My GPU is an AMD Radeon RX 6800 so I doubt thats the issue. Any idea what is wrong?
Try updating your gpu driver (adrenalin software).
One of the recent driver updates broke most godot games using vulkan, I believe it affected cards older than the 7000 series but I'm not entirely certain. Or you could try the dx12 version.
