Q Light Controller+

Case of use:
In inputs / outputs, in profiles tab

Select any profile (in my case an OSC profile)

Open the profile editor and do not touch anything

Just minimize qlc +, from the window manager's minimize button, or from the
taskbar of your O.S

Qlc + whole freezes and ends up disappearing

It also happens if you put another application above or by maximizing the window of another application (Web browser, text editor)

This error has happened to me with Lubuntu 16.04, ubuntustudio 18.04, linuxMint cinnamon and with Qlc 4.11 and 4.12 Git
I do not know if it will happen the same in other S.O or of who can be the error "QLC or of the O.S or of the manager of windows of turn ..."

The attachment is a simple compressed text file with a copy-paste
of the error message, it is very long and I thought it would be better to send it like this so as not to fill the forum with error messages
a greetings

It could be a solution that the input profile editor is a stand-alone application, such as the Fixture editor ...
I do not know if something like this would work, it just happens with the profile editor running ...
