Problem: With a non-zero 'autocompletedelay', Insert-mode autocommands
(TextChangedI, TextChangedP, CursorMovedI) are delayed, and
while typing faster than the delay they are dropped entirely,
because the delay blocks the main loop.
Solution: Make 'autocompletedelay' non-blocking: instead of busy-waiting
before showing the popup menu, defer it with an input-wait
timeout (K_COMPLETE_DELAY) modeled on CursorHoldI, so typing
stays responsive and the Insert-mode autocommands fire normally.
The delay timer coexists with 'updatetime': the main loop waits for the
sooner of the two and triggers the event whose deadline was reached, so
'autocompletedelay' no longer shadows CursorHold timing. Changing the
completion leader, for example with Backspace, updates the visible popup
immediately like a zero delay; only the first popup is deferred.
Update the 'autocompletedelay' screendumps for the non-blocking display.
One test opened the menu with CTRL-N right after the delay expired and
could race with the deferred popup, so it now waits a little longer than
the delay before sending the key.

Install from source
See BUILD.md and supported platforms for details.
The build is CMake-based, but a Makefile is provided as a convenience. After installing the dependencies, run the following command.
make CMAKE_BUILD_TYPE=RelWithDebInfo
sudo make install
To install to a non-default location:
make CMAKE_BUILD_TYPE=RelWithDebInfo CMAKE_INSTALL_PREFIX=/full/path/
make install
CMake hints for inspecting the build:
cmake --build build --target helplists all build targets.build/CMakeCache.txt(orcmake -LAH build/) contains the resolved values of all CMake variables.build/compile_commands.jsonshows the full compiler invocations for each translation unit.
