I don't know exactly how ruby's threads interact with wx's scheduling. Perhaps you could try adding an evt_idle handler to your example?

For me this does what I'd expect: fire regularly  and spawn and run threads fine. What I didn't expect, but that happened anyway, is that your original long-running Thread now also seems to run regularly regardless of app focus. Maybe add an explicit call to thread.run() in the on_idle handler?

require 'thread'
require 'wx'

class MinimalApp < Wx::App
  def on_idle
    Thread.new do
      puts 'FOO'
      STDOUT.flush
      sleep(1)
    end
  end

  def on_init
    evt_idle { on_idle }
    f = Wx::Frame.new( nil, -1,'Test' )
    f.show
  end
end

$t = Thread.new do
  loop {
    puts 'BAR'
    STDOUT.flush
    sleep(1)
  }
end

MinimalApp.new.main_loop
