Comment (by wagon):

 Thank you! Now everything works, but we are probably moving to the stage
 "old bugs fixed, new bugs added".

 Stable version (2.0.4) didn't have artifacts during startup. Git version
 has. I think it is related to your fixes to panels (which were crashing
 during scrolling). I'll attach screenshot. Left scrolling panel is
 connected to upper symbols, some words are changed (`hidden]n]` instead of
 `hidden]`, and `file.e` instead of `file`). I checked few terminals, and
 it is everywhere. It is easily fixed if after startup I refresh the
 terminal with Ctrl+L, but should it be fixed anyway?

 Another thing is more essential: stable version displayed cpu usage by Tor
 and its uptime, but git version doesn't do that. cpu is always 0.0, uptime
 value is empty. However, if I use root to run git version of Nyx, both cpu
 and uptime are shown. It looks like permissions issue, but everything else
 works OK, and I failed to find what's wrong with my setup (stable Nyx
 worked good also with non-root user).

 I think it would be good to have Nyx version also shown at the top. Now it
 can be accessed through menu, but since you write 'nyx' at the left top
 corner anyway, why not to add its version too? With `tor-prompt` it is
 worse: I cannot see any way to learn its version, even as command-line
 switch.

 Both git and stable `tor-prompt` have one strange behavior:
 {{{
 $ tor-prompt
 Tor isn't running. Starting a temporary Tor instance for our interpreter
 to
 interact with. This will have a minimal non-relaying configuration, and be
 shut down when you're done.

 --------------------------------------------------------------------------------

 Unable to start tor: Process terminated: Failed to bind one of the
 listener ports.
 }}}
 But:
 {{{
 $ tor-prompt -i 127.0.0.1:9051
 Welcome to Stem's interpreter prompt. This provides you with direct access
 to
 Tor's control interface.

 This acts like a standard python interpreter with a Tor connection
 available
 via your 'controller' variable...

   >>> controller.get_info('version')
   '0.2.5.1-alpha-dev (git-245ecfff36c0cecc)'

 You can also issue requests directly to Tor...

   >>> GETINFO version
   250-version=0.2.5.1-alpha-dev (git-245ecfff36c0cecc)
   250 OK

 For more information run '/help'.

 >>>
 }}}
 Why it doesn't recognize standard port as its default? Is it a bug or
 feature? If it is the feature, I would make the default to be the
 opposite: if somebody wants to start extra Tor, he should specify some
 command-line option.

 And the last thing is wrong Nyx log messages (problem exists for both git
 and stable):

 {{{
 [NYX_NOTICE] Unused configuration entry: unicode_support
 [NYX_NOTICE] Unused configuration entry: data_directory
 [NYX_NOTICE] Unused configuration entry: acs_support
 }}}

 At first, Nyx always says that these options are "unused" independently on
 the value in `nyxrc` config (`true` or `false`). My terminal has unicode
 support, everything looks OK with pseudo-graphics, so I cannot understand
 why it is "not used". When I disable `acs_support`, pseudo-graphics is
 replaced by other symbols, so this option works. But NYX_NOTICE is always
 "unused" for both `acs_support false` and `acs_support true`. Maybe you
 have added these options, but forgot to update Nyx config validator?
