My recommendation fix for this is use a value to accumulate the delta size and round it by 120 for every 5% change (or maybe 36 for 1% change), when the accumulated delta reaches the certain point, do the actual volume update. Reproducible: Always Steps to Reproduce: 1. Use plasma 5 2. scroll with modern synaptic touchpad Actual Results: The volume change too fast. Expected Results: Volume changes more steadily. 1492578 1 esken 2015-01-20 20:17:45 +0000 @Weng Xuetian: Thanks for your help. I am currently doing a start-of-year swipe of tickets and reviewboard for KMix. I will do some tests, but will likely apply your patch soon. 1492591 2 esken 2015-01-20 21:11:33 +0000 Git commit e318bedab3022b2972f0fe9699529afa75d68372 by Christian Esken.

I'm still having this problem in KDE5 (plasma-desktop version 4:5.4.2-0ubuntu2).
