public sealed class GpuTimelineViewA frame's GPU passes, as a bar each.
No guide page documents this yet — the page shows what the code says about itself.
Remarks
The panel is GpuTimelineView.vxml; this file is the accessibility modifier and the two records the markup's snapshot is made of. The emitter's partial has no modifier, so a type another assembly holds — and Vixen.Editor.Diagnostics and Vixen.Editor.App.Tests both hold this one — needs a declaration that says public. Same arrangement as MemoryView and StatisticsView.
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.
