New question #703904 on SikuliX:

We’ve been trying to get SikuliX 2.0.5 to run on a RHEL 8 system, and not
having much luck.
We went through the instructions on this webpage:
https://sikulix-2014.readthedocs.io/en/latest/newslinux.html#newslinux
We started on RHEL 7, but the OpenCV shared library required a newer version of
GLIBC than is standard on RHEL 7 (version ‘GLIBC_2.27’ not found (required by
~/.Sikulix/SikuliLibs/libopencv_java430.so)), so we moved up to RHEL 8. We had
to build OpenCV (v4.3.0) from source because we could not find a java companion
package for RHEL 8, which required quite a few other dependencies, but in the
end we got it built with most options enabled, and installed as root on the
system. We also got Tesseract installed via a package, as well as xdotool and
wmctrl.
We are setting LD_LIBRARY_PATH to ensure that the OpenCV libs are picked up,
and when we run with the “-v -c” options to the IDE, there are no obvious
problems reported. It seems to believe it is moving the mouse, though we can
see that it is not, and when we try to capture a screenshot, the “canvas” from
which to capture is either uninitialized/garbage frame buffer memory, or a
totally black screen. On rare occasions we have seen the actual desktop, but
most times we do not.
Originally the system had 2 monitors, but was subsequently reconfigured to a
single display system. We were originally running remotely over NoMachine, but
have also tried running locally and observed no difference in behavior.
Any pointers or suggestions would be most welcome. Given that no error messages
are being reported, we are out of ideas for how to proceed in debugging the
problem. It appears that more native support is provided for Debian-based
systems, but we’re attempting to validate a product which only advertises
support for RHEL systems, so we’d prefer to get it working in this environment
if at all possible.
