The denominator subtracts context switch sample counts from total sample counts, both for the whole trace and within the range filter. The subtraction could underflow: on traces with inconsistent sample ordering the binary searches over the unsorted sample vectors can return too few samples, and a sample which arrives with a duplicated timestamp is merged into the existing entry while its context switch classification is still recorded, so the context switch samples are not a strict subset of the samples. An underflow made every percentage in the table display as zero. Clamp the subtraction, per thread in range mode, so that one thread with bad data does not affect the counts of the others.
Tracy Profiler
A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
Tracy supports profiling CPU (Direct support is provided for C, C++, Lua, Python and Fortran integration. At the same time, third-party bindings to many other languages exist on the internet, such as Rust, Zig, C#, OCaml, Odin, etc.), GPU (All major graphics/compute APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA, WebGPU.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
