In the schematic, canvas zoom via scroll wheel is misconfigured, it requires multiple clicks of scroll wheel in a short time to change zoom level. This works fine on PCB and 3D view, it appears to be related to the mouse settings on the device, specifically how many lines to scroll with each click of scroll wheel, if 3 lines are selected then the schematic works as expected, if 1 line is selected then a scroll event does nothing, only when multiple scroll events occur in fast succession will the canvas zoom. Feature request: setting to change how much to zoom with each scroll wheel click, slider % of current zoom, individual to schematic or PCB?
