Have you actually tested a wx build with this enabled?

Comments in that ticket suggest that XTest doesn't work on Wayland and
"Wayland is used by default in Debian 10 and newer" (10 is buster, the
current stable release right now which is about to become oldstable):

https://wiki.debian.org/Wayland

It looks like there isn't a Wayland-specific implementation in the
source and src/unix/uiactionx11.cpp uses X11-specific functions so
building with --with-xtest may not really solve your problem.

Forcing use of X11 for the app may help, e.g.:

  GDK_BACKEND=x11 ./myapp

(The debian wx packages currently effectively do the above automatically
if wxGLCanvas is used as the current support for wxGLCanvas on Wayland
has some problems - hopefully we can eliminate that soon, but it seemed
the least risky fix for the bullseye release.)

Hilarious, but more useful answers to these questions would be a
short python script to allow us to easily check if wx.UIActionSimulator
is working as you expect or not (e.g. currently this script produces
no output, with working support it should output "...").

I notice that configure --help describes this feature as "experimental":

  --enable-uiactionsim    use wxUIActionSimulator (experimental)

That might be an outdated status though.

Cheers,
