Description Tobias Wenzel

+++ This bug was initially created as a clone of Bug #53907 +++

After switching from iTalc to Veyon, there is a delay in image transfer on a teacher PC in presentation mode.

This delay does not exist on client computers.

When updating to a newer version, I received an error when I opened the computerroom module because Veyon is not running:

univention-app logs  ucsschool-veyon-proxy
#### 'docker logs 2a1fb35f0692b13f5c0f2a573d3dcccbd97cdf478113a95628af74deb5f76217' output:
QThread::start: Thread creation error (Operation not permitted)

This is connected to the version being too low:

docker -v
Docker version 18.09.7, build 2d0083d

It looks like the problems could also be fixed with the upcoming documentation for the Veyon Master.
