IRSIM
Known Issue. No output on analyser (see screenshot1.png)
If you struck against a no output on analyser, this is because the background is
being drawn white, and the traces are drawn white, so the result is white-on-white,
and invisible! The display was being redrawn.
The Tcl/Tk version was hacked on top of the X11 version, and some things aren't
properly configured for Tcl/Tk. In Magic and XCircuit, the X defaults has been
moved to Tcl, where they are read from a Tcl script. In IRSIM, the properties
are still controlled by X11 and the X11 resource manager.
The white-on-white probably comes from a default .Xdefaults or possibly
.Xresources setting "*background: white" which makes all backgrounds white by
default.
You can avoid this by adding to your home .Xdefaults file:
irsim.background: black
and then reloading with "xrdb -load .Xdefaults".

Meanwhile, upstream is working to find a fix.
