Blank screen in acm

[Ken Sharp]

It's not exactly a blank screen but nothing useful draws (see screenshot).

Confirmed in Quantal.

I have the same issue on Ubuntu 12.04 amd 64. When I run acm on terminal, I get:

An upstream bug report implies it's abandoned and a somewhat newer fork is available: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=362023

Another bug refers to it crashing: http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=715616
I can't get it to crash, just the screen as in #1. To test for the upstream bug exit value:
acm ; echo $?

Tried working around the sound problem with pasuspender, padsp, and aoss to no avail. Looks like it uses libaudio:

Some more reports in reviews: https://apps.ubuntu.com/cat/applications/precise/acm/

A reviewer suggested hitting random keys to get it functional. I found that pressing "r" will get it to show the primary view. Pressing "k" will start joystick calibration mode (doesn't seem to be a way to cancel it if you don't have joystick). Some of the cockpit controls will individually become visible if you adjust them with the keyboard. Definitely a video initialization problem in addition to the sound problem.

This bug was fixed in the package acm - 6.0+20200416-1ubuntu1

---------------
acm (6.0+20200416-1ubuntu1) hirsute; urgency=medium

  * Merge from Debian unstable (LP: #1015343). Remaining changes:
    - debian/control: Improve clarity of description.
  * Dropped change to call fclose in src/main.c (no longer applicable).

acm (6.0+20200416-1) unstable; urgency=medium

  * Switch to new upstream source,
    http://www.icosaedro.it/acm/download.html. (Closes: #362023)
    Also does not exhibit some "black screen" behaviour from the
    previous version. (Closes: #765815)
  * Take opportunity to switch to source format 3 / quilt.
  * Patch inventory.c for format errors. Using changes suggested by
    upstream, thank you! (fix_inventory.patch)
  * Fix enum so that acm builds. (fix_mouse_stick_mode_enum.patch)
  * Set directories for Debian filesystem (set_default_object_dir.patch
    and fix_paths_in_acm_tcl.patch)
  * Revise build-depends for substantially revised upstream code.
  * Add some hardening (hardening1.patch).

acm (5.0-30) unstable; urgency=medium

  * Fix FTBFS with gcc-10. Due to variable hasFired in aim120.c that
    should be static. (Closes: 956978)
  * Add <string.h> to radar.c.
  * Bump standards-version to 4.5.0.
