Linux - internal function call issues

[oldgearguy]

I have a panel that has a uiButton for MIDI configuration. The button has the "Component Generic"/Internal function this component should execute field set to: MIDI Device Selection.

This works perfectly 100% of the time in Windows and Apple environments. In Linux, you need to continuously click on the button and maybe once every 15/20 clicks the menu will pop up. Sometimes you just get a beep, sometimes nothing. Even adding a (temporary) hot key combo did not help.

Is there a special Linux setting or some other thing I should do to get this to work?
(I have an alternate approach - create a restricted instance with a menu bar, but I'd rather not do that if I don't have to, especially since it's only for the Linux version).

Is it a uiButton and not a uImageButton?

[oldgearguy]

It's whatever. I didn't have a definite implementation yet. If it's too involved or hard to extend, I'll just do it with a uiSlider and an image rectangle.

I'll take a look at the examples you and Damien posted.

I tested it in Fedora 43 - it seems to be working for me.
