Your sentence that says "when you can't reproduce such an apparently obvious issue" that makes it sound as if I'm doing something wrong. It's clear you intend to say that you cannot reproduce the issue but your phrasing could be improved.
I do not have a joystick. The keyboard is attached to a laptop. I have not tried the game recently on another computer but if I get the chance I will. As I wrote before, I believe I have already seen this issue on multiple machines (likely on another Dell laptop at minimum) but it's been a long time since I would have tried and I don't recall anything for certain. As for seeing more people report the bug, this an an obscure game. When you start with the small fraction of people running Debian and multiply it by the fraction of people who actually install this game and then multiply by the fraction of people who experience the bug, and then multiply the fraction of people who report bugs (which is canonically taken to be about 1 in 100 users) , you are getting down to a small number of expected bug reports... perhaps on the order of one like just me. While it's interesting that you do not experience the bug, I assure you the bug does happen for me; and your message almost makes it sound like you dismiss the concept of bugs that depend on various external issues or even hardware. It's far from obvious to me that we should have seen more confirms in this case and I also note the lack of additional "works for me" comments. So please don't dismiss my report as if you are sceptical of the problem that *I'm* experiencing because just because you don't see it. Jason
