Based on my testing, every so often cwtch will launch and be stuck on the splash screen for far longer than normal - up to a minute.

My guess is there is some subtle asynchrony issue which every so often forces the splash screen to wait a long time for the clear message - perhaps an event bus flood?

This has little impact except annoyance and the occasional failed pipeline test (because splash screen dismissal times out at 10 seconds)

My experience is that cwtch does take a long time to get past the splash screen, but took 1m22s to display the purple screen at all - the splash screen gives way to the program itself after a total of 2m22s. Testing again gives values of 1m9s for a blank screen, and the graphic appears until a total of 2m12s have passed.
Running cwtch from the terminal returns...

my_application.cc: using aot_library_path or '/usr/lib/cwtch/libapp.so'

...and remains onscreen for 1m6s. After this, the following appears as the splash screen shows up.

Update on this based on yesterdays research:

This is caused by Cwtch being unable to connect to a Tor process. It can happen for a few reasons:

Another process is using the same Tor data-dir (this causes a ~5 second delay)
Cwtch is configured to use a specific tor process control port, and that port is unavailable/clashing with another process (this delay can be anywhere from 30 seconds to 5 minutes depending on the specific OS configured socket timeouts)

The solution to this is a change to autobindings to rework the setup so that the splash screen logic no longer depends on connecting to Tor. This used to be a big problem, but after recent changes to how protocol engines are created and initialized should be pretty easy to fix.

Any Tor errors will then only be surfaced on the Tor config page.

This should get in 1.12
