Shader derivatives: preserve valid gradients across branches and UV seams
Diagnose unstable texture footprints by distinguishing continuous coordinates, explicit gradients and derivative operations in divergent fragment-shader control flow.
-
Shader variants and prewarming: reduce first-use stalls deliberately
Separate variant selection, build stripping and pipeline preparation; design a measured warmup policy that covers real rendering states without assuming every stall disappears.
