Summary
Problem
Some systems exhibit rendering artifacts where content at Y=0 becomes invisible when the canvas buffer exceeds certain dimensions, even when within WebGL's reported MAX_TEXTURE_SIZE limits.
Solution
Cap the WebGL buffer dimensions to 4096px maximum. The CSS display size remains unchanged - the buffer is simply rendered at lower resolution when the viewport is very large, then CSS-scaled to fill the container.
