Can you confirm whether my recommendation below fixes the issue on your
machine?

This is apparently necessary on RHEL/CentOS 7 and 8 as well. Under
prior RHEL/CentOS releases, the initrc_t context was unconfined, but
apparently that changed. On my Fedora 34 installation, it is also
necessary, so I'm not sure how you were able to make the TurboVNC
Server init.d script work on Fedora 34. I'm investigating whether it
makes sense to relabel /etc/rc.d/init.d/tvncserver automatically in
the official RPM. Everything I've read so far suggests that
unconfined_service_t is the appropriate context, since that context
was designed for running non-SELinux-aware services.

Try
sudo semanage fcontext -a -t bin_t /etc/rc.d/init.d/tvncserver
sudo restorecon -R -v /etc/rc.d/init.d/tvncserver
and then reboot the system. That seems to work for me. Those
commands have the effect of making the TurboVNC Server init.d script
run under the system_u:system_r:unconfined_service_t:s0 context
instead of the system_u:object_r:initrc_exec_t:s0 context, which more
closely simulates the SELinux context that you get when you start the
TurboVNC Server manually (unconfined_u:unconfined_r:unconfined_t:s0).

Hello,
I upgraded a machine from fedora 34 to 35. After that, I got a black
screen in the turbovnc client.
If I start turbovnc server manually in a shell, the vnc server starts
fine, and I can connect.
Then I tried "setenforce 0", and started the turbovnc service, and then
xfce starts fine, and I can connect the client. I can then turn on
selinux again, and it seems to continue to work.
I also upgraded turbovnc turbovnc-2.2.91-20220224.x86_64
but that didnt seem to make a difference.
Any hints how to fix this?
