I just switched from ubuntu-desktop to xubuntu-desktop (which, by the way, has greatly improved my performance). Previously, when using “regular” Ubuntu, I was able to adjust individual tracks’ height by using ALT+Scroll Wheel. However, this operation now seems to activate the DE zoom level, rather than adjust the track height. Could it be that I have to set Ardour to override my DE settings? Any help much appreciated. Please see included video for a demonstration of what happens. Many thanks in advance!
