Expand description

Retained widget backbuffer state shared by software and GL implementations.

Fields§

§cache: BackbufferCache§dirty: bool§width: u32§height: u32§spec_kind: BackbufferKind§theme_epoch: u64

Visuals epoch recorded the last time this retained surface was repainted. Retained backend layers compare it against the live theme epoch so a dark/light flip rebuilds the window/layer in the shared paint path.

§typography_epoch: u64

Typography epoch recorded the last time this retained surface was repainted. Without this, a clean parent FBO can keep compositing old text after global font/LCD settings change.
