For a long time I would run into a weird problem when dragging files around in dolphin, where the files I’m trying to drag would mysteriously open during the operation. This was particularly annoying when I had selected a lot of large files which opened in a slow app by default.
I’m now pretty sure that this was being caused by dolphin’s “open in secondary app on middle click” feature, combined with accidental triple (middle) click gestures being triggered while dragging on my trackpad.
I have no interest in using middle click for anything, is it possible to disable this feature in Dolphin? Or, if not, to turn down the sensitivity (or maybe even disable middle click gestures altogether) in libinput? I’m using Plasma Wayland on Kubuntu, if that’s relevant.
