It's a minor convenience thing, no big deal:
I have a Logitech G610 keyboard (cherry mx brown, but that's besides the point) with physical/dedicated multimedia keys.
I noticed that after starting MM, when I hit the play/pause button, the playback starts for a fraction of a second and immediately stops as if the key press was registered twice. After that, pressing the button works as expected. I tried this multiple times, and It happens consistently, so I don't think it's a faulty physical button. It doesn't happen with another media (video) player I use, Daum PotPlayer, so I don't think it's a windows update thing that broke something - at least not consistently across all apps.
Maybe it's related to
this issue? I don't know.
Edit: After answering phred's question below I noticed that in addition to this only happening once after starting MB, it only happens if MB is in focus. To recreate, I start MB, make sure it's in focus, press the play/pause physical key. Instead of playing, I can hear music for a fraction of a second, and also the play (triangle) button in the MB player controls changes to pause and back very quickly. additional key presses work just fine whether MB is in focus or not.
Another edit: Another thing I just tried: Start MB. Use the mouse the play and pause. Only then hit the physical multimedia key. Same thing happens, it registered twice (plays and pauses). Also, if I start MB, use mouse to hit play, then hit the physical multimedia key: it registers twice, pausing and starting playback right back.
I updated the topic title to better reflect the issue in light of those experiments. I hope this helps.
