http://bugs.winehq.org/show_bug.cgi?id=57031 --- Comment #10 from Andrei <funnylittleelephant@proton.me> --- Sorry, the fix I described in my previous comment was actually a workaround, and the distinction between DirectInput 7 and DirectInput 8 seems truthful to what Windows library does. It works, but it doesn't address the root problem. I dug deeper using Claude and it looks like Rémi Bernon's change in 5b833c83 was an optimization which opened two races. The serialized behavior is what Windows did prior to DirectInput 8, so games that relied on it worked fine, but the optimization allowed essentially stale state of the cursor to affect the deltas, therefore mouse jittering. I managed to fix the races with Claude, or at least it now works for me, without removing the `if (dinput->dwVersion >= 0x0800)`, attaching an updated AI-generated summary. -- Do not reply to this email, post in Bugzilla using the above URL to reply.
