Description Patrick Silva 2022-02-12 12:12:21 UTC 
STEPS TO REPRODUCE
1. play a video in youtube with Firefox
2. repeatedly pause/play the video with middle-click (I use a touchpad, middle-click with two-fingers tap) on Media Player applet in system tray
3. 

OBSERVED RESULT
after middle-click on Media Player applet, playback pauses/resumes as expected and sometimes an OSD showing the volume of Firefox appears 

EXPECTED RESULT
volume OSD should never appear after middle-click on Media Player applet

It sounds like you are triggering a scroll, which then changes the volume and makes the OSD appear
Comment 2 Patrick Silva 2022-02-12 13:30:22 UTC 
You are right. OSD does not appear when scrolling is set to 'Touchpad edges' instead of 'Two fingers'.
There is something wrong with my touchpad or libinput because frequently a webpage scrolls up in the internet browser when I try to open a link in background doing middle-click with two-fingers. This behavior occurs even on Gnome.
Comment 3 Patrick Silva 2022-02-12 13:54:00 UTC 
The weird thing is that the volume level does change when the OSD appears.
Comment 4 Patrick Silva 2022-02-12 14:01:43 UTC 
ops, if the volume is less than 100%, sometimes it increases 1% or 2% when the OSD appears.
Comment 5 Nicolas Fella 2022-02-13 01:46:38 UTC 
It seems to me that Plasma works as expected then? Or am I missing something?

Confirmed libinput bug.
