+++ This bug was initially created as a clone of Bug #52521 +++ The veyon client will be used in a threaded environment (The UMC Computerroom module) and thus needs to be threadsafe. We need a test for this.
I used the test code from bug 52521 in comment 5 for this fix [twenzel/4.4/veyon_client_thread_test] e9fd99cde Bug #53019: test veyon client thread safety
Looks fine to me. I merged it into 4.4 and did some test builds on a VM. I am setting the Bug on VERIFIED.
