 This is apparently a security enhancement. In its infinite wisdom Google has decided to not give you any option to bypass this restriction.
 
+\subsubsection{Limitations}
+
+When using Tracy Profiler, keep in mind the following requirements:
+
+\begin{itemize}
+\item Each lock may be used in no more than 64 unique threads.
+\item There can be no more than 65534 unique source locations\footnote{A source location is a place in the code, which is identified by source file name and line number, for example when you markup a zone.}. This number is further split in half between native code source locations and dynamic source locations (for example, when Lua instrumentation is used).
+\end{itemize}
+
 \subsection{Check your environment}
 
 In order to get the most accurate profiling results you should minimize interference caused by other programs running on the same machine. Before starting a profile session close all web browsers, music players, instant messengers, and all other non-essential applications like Steam, Uplay, etc. Make sure you don't have the debugger hooked into the profiled program, as it also has impact on the timing results.
