--- Comment #1 from Peter Rathlev peter@rathlev.dk --- I have what I think is the same problem, though using camera panning in Kerbal Space Program instead.
Testing from a text VTY with "evtest" shows seperate events on press and release for all buttons, including the middle trackpoint button. But testing with "xev" in a running Xorg session only fires events on release (though both press and release are then logged) when using the middle mouse button.
So it seems like the kernel does things right, but somewhere on the way to X something stops working. I have only today upgraded to Fedora 26, so I don't know when the problem appeared. I have not seen the problem with Fedora 25. While searching I stumbled upon bug 1482640, but I have no idea it it's related.
How does one debug further on this? Specifically whatever is between what evtest reads from (kernel?) and what xev reads from (Xorg?).
(And this is like _super_ critical, not being able to play Kerbal Space Program to its full extent is a big problem. ;-])
