SUMMARY Zooming by CTRL+scrolling on a touchpad with granular scrolling only works if you do it so fast you have almost no control over the outcome. STEPS TO REPRODUCE 1. Have a touchpad with high resolution scrolling support (scroll delta < 120) 2. hold control key and scroll in any directory in dolphin 3. it does not respond at all when scrolling slowly, no matter how far you try to go. OBSERVED RESULT When scrolling slowly it completely ignores that, no matter how far you 'scroll'. It only responds if you go so fast you're not able to stop at the zoom level you want. EXPECTED RESULT Zooming should work like everywhere else, eg firefox.
