This is hard to report but I am going to try. First, I installed FreeBSD 13.1 and Openbox/LXDE. Then I installed an external port of the Palemoon browser. By "external" I mean it is provided by a third-party. When I scroll the mouse wheel in Palemoon, the browser navigates back and forth in the tab's history, as if I was clicking "Back" and "Forth." Actually, it only happens when I scroll up and a bit too fast. First it will go "back" then it will go "forth." I thought it could be a problem in the Palemoon port, but then I noticed it happening in the PCmanFM tabs. Only instead of going back and forth in navigation history, tabs would be selected (previous/next) when I scrolled up a bit too fast. So I thought it was my Openbox configuration, entirely imported from a Linux installation (although that never happened in Linux). I spent quite some time editing my Openbox configuration in the attempt to fix the issue, but to no avail. Since I have other problems with Openbox in FreeBSD (all reported in the forum, one was denied by multiple users and two have had no reply so far), I just gave up. Now here is the kicker. Then I installed NomadBSD. I know you don't support NomadBSD, but the problem also happens there in Openbox, with a default configuration (I brought NOTHING from my Linux configuration to NomadBSD) and on Firefox. A FreeBSD derivative, a nearly default Openbox configuration (I just changed themes) and a different browser. The only common denominators are FreeBSD and Openbox. I'm not sure anyone will be able to reproduce this, but it is reported.
^Triage: try to rescue this PR from obscurity. I'm going to assume the actual report is against x11-wm/openbox. It is certainly not against the infrastructure.
(In reply to Luc from comment #0) That indeed sounds tricky to reproduce. I use openbox and firefox and never noticed problems like that. Two questions: 1. Could you run xev(1) (x11/xev) and see if there's a difference in how it sees a normal scroll and a "a bit too fast" scroll? 2. Is the problem reproducible if you run "standalone" openbox (without LXDE)? BTW, could you also share links to the other 2 issues you mentioned?
