The topmost scanline is where it should be, the next one is offset by 2 pixels to the left, next one by 4 pixels to the left, and so on, which creates a triangular-shaped mess of pixels.
Core version is 1.60 dad0ae5 on Android, using the GL backend.
Vulkan backend works fine, although is a lot less performant, at least on my device (Huawei Mate 20x, Kirin 980, Mali G76 MP10).
