Comment 19 for bug 367049

My (HP laptop) keyboard also causes the lag on notify-osd, and it's particularly bad when at minimum or maximum volume -- it's actaully faster to kill notify-osd than to wait for it to stop spazzing.

I have attached a log of my keyboard behavior ( xev | grep --line-buffered KeyPress | ts %.S | tee keyrepeat.log ) -- as you'll see, it repeats every 0.05 (1/20) second or so. It seems notify-osd can't cope with this rate of key repeats... and because notify-osd lags at displaying the volume change, the sound volume itself lags at changing. That's an entirely different issue, however (and it's synchronous "by design").
