public sealed class GpuTimelineView

A frame's GPU passes, as a bar each.

No guide page documents this yet — the page shows what the code says about itself.

Remarks

Deliberately not a second flame chart. GPU work is a sequence of passes rather than a call tree — a pass has no caller and nothing runs "inside" another pass in any sense a timestamp can see — so a control that drew rows of nesting would be inventing structure that is not there. What a debug group gives is one level of grouping, which is what Level carries.

⚠ It says when the device cannot be timed rather than drawing nothing. Doc 20's B4 names timestamp queries as this panel's dependency and several real configurations do not have them — MoltenVK's statistics, GLES, WebGPU without the feature — so an empty chart would be indistinguishable from a frame with no passes in it.

⚠ The frame it shows is several frames old, and the label says which. Reading a query pool the GPU has not finished writing would mean stalling the frame thread on the device once per frame; GpuProfiler refuses to, so what is on screen is the oldest submission that has retired.
