Tracy requires some textures to have repeat wrapping mode set. The ImGui
implementation of samplers doesn't make it easy to achieve. Disalbe use
of samplers and rely on texture flags, as done originally.
Bug (High Severity): Wrong queue type in MemDiscardCallstack
In the callstack path of MemDiscardCallstack, the wrong queue type is
sent:
SendMemDiscard( QueueType::MemDiscard, thread, name );
Every other callstack variant correctly uses its callstack queue type
(MemAllocCallstack, MemFreeCallstack, etc.), but this one uses the
non-callstack type. The SendMemDiscard assertion at line 1026 confirms
MemDiscardCallstack is a valid value.
Impact: The callstack captured by SendCallstackSerial() will be orphaned.
The server processes the event via the non-callstack handler, leaving the
callstack serial data unconsumed, which desynchronizes the serial queue
and corrupts all subsequent events.
A zone emitted from a shared object initializer runs before the
executable's constructors, so its timestamp precedes s_initTime, which
the server uses as the trace epoch (baseTime). Such a zone converts to
negative trace time and its end no longer satisfies IsEndValid(), which
excludes it from statistics reconstruction and makes it render as
never-ending.
Record the current time when a producer token is created before
s_initTime is constructed and use it as the init time, ensuring no event
timestamp precedes the trace epoch.
ELF init_priority only orders constructors within a single module. All of
a shared object's initializers run before any of the executable's, so an
instrumented dependency .so emitting a zone from its static initializer
creates the main thread producer token against the zero-initialized
s_queue. The queue constructor then resets the producer list, orphaning
that producer: every zone emitted on the main thread from that point on
is enqueued into blocks no consumer ever iterates and silently lost,
while sampling (worker thread producer) keeps working.
Re-link such a producer right after the queue is constructed. In the
common case, where nothing was emitted during shared object init, this
merely constructs the main thread token eagerly.
