I just tested this in a VirtualBox MX-19.1 installation. What I did was add
Code: Select all
#deb http://mxrepo.com/mx/repo/ temp main
to my /etc/apt/sources.list.d/mx.list (editing that file as root) then temporarily enabled it in MX Repo Manager, right-clicked on my MX Updater icon in the panel, checked for upgrades, applied them, then disabled the repo again in MX Repo Manager instead of leaving it permanently enabled (I'm paranoid about permanently enabling any kind of testing repos.)
My results, after logging out/in, is that I no longer get scrolling arrows when right-clicking on text files, most archives, directories, etc, but I do get them the first time I right-click on a music, image or video file, but if I dismiss the action menu and right-click on one of those files a second (third, fourth, etc.) time I no longer get them. This only works in my current login session though: if I log out or reboot the scroll arrows are back, only for files with certain mime types, and only the first time I right-click on them in that session.
It's way better than it was.
Edit: I also installed this on my production system just now, after having tested it in two VM installations of MX.
