Public bug reported:
QLC+ was working fine on Ubuntu 24.04, but shows this issue after
upgrading to Ubuntu 26.04:
Every change takes dozen of seconds to take effect. When I select a
scene, it took 14 to take effect. Sometimes QLC+ can stop working
completely.
I have a Eurolite DMX512 Pro device using the "DMX USB" plugin.
I just downgraded qlcplus to 4.12.7-1build4 and it started to work
correctly again. Then I started to bisect the problem and QLC+ 4.13.0 is
the first upstream release to show this problem.
