Bug ID: 56492 Summary: Wine 9.5 breaks Opentrack/TrackIR head tracking, works in 9.4 Product: Wine Version: 9.5 Hardware: x86-64 OS: Linux Status: UNCONFIRMED Severity: major Priority: P2 Component: -unknown Assignee: wine-bugs@winehq.org Reporter: fell@fellr.net Distribution: ---
After updating to Wine 9.5 I noticed that the Wine plugin of the Opentrack head tracking software wasn't working any more. It simply couldn't "connect" and displayed "waiting for game..." forever. After reverting back to Wine 9.4 it worked fine again.
Corresponding issue at the Opentrack project: https://github.com/opentrack/opentrack/issues/1827
Observed behavior: After pressing "Start" the tracking does not work game and "waiting for game..." is displayed in the Opentrack title bar.
Correct behavior: After pressing "Start" the tracking should begin in the game and the game name should be displayed in the Opentrack title bar.
Now, I don't know how exactly that plugin works and how it communicates with the game. It is using the TrackIR/Freetrack protocol which seems to rely on some kind of direct memory access, but I'm not sure.
