Here are some of my hardware information:
CPU 12th Gen Intel(R) Core(TM) i5-12400F
GPU AMD Radeon RX 6600
Would you need anything else?
So what i've heard is that most AMD users suffer from this glitchy graphics because of the new integration of Vulkan in Godot. Some soluctions are redering the game into compatibility mode or change the rendered from vulkan to D3D12
At least that what it helped me.
