It's not any serious issue, just wanted to report. In fact I personally don't see any use of this plugin but that's probably just me. :P

On Linux I cannot reproduce it, neither in my docker build with current master (07888a2e90827605cbc46f25e2124f3b4b1cdb14), nor with the latest nightly appimage (21fb8e2). The Mixer Slider works fine.

I cannot reproduce it either... Let's close the bug for now.
