Q Light Controller+

I've got a problem using Submaster.

On my Virtual Console, I have some buttons launching different collections.

When the launched collection contains a Chase, the submaster works great but when it contains a sequence, it does'nt work.

If I move the Submaster, the Dimmer reduces but as soon as I release the slider, it goes back to 100%.

It seems it was a regression since an old post talk about that here :viewtopic.php?t=7768

It was solved in 2015 but seems to go back.

Anybody can help ?

My config is :
Windows 10
QLC+ 4.11.0

Are they both placed in a frame?
What do you mean with 'when I release a slider' -> when you don't touch a slider it stays in that position... (unless it's motorised and there is a feedback to it ...)
Please attach your show-file (and eventually fixtures)

Yes, buttons and submaster are placed in the same solo frame.

I attach a light version of my project (just with PAR) and fixture.

If you click button "All On", submaster works great but for all other buttons, submaster is ignored (it work when you move it but intensity goes back 255 as soon as you stop moving submaster slider).
