Can you try disabling any sort of mouse acceleration? Perhaps that might have an effect...
I ran some more testing and it appears to be NOT a wine related problem but a hardware related problem with Linux. I loaded up Minecraft and Garry's Mod and a very similar issue happens, though nowhere near as borked as it occurs on Thief Gold. Every once in a while on Garry's Mod my aim will randomly stutter/go back for a second if I move the mouse in a direction, its almost like it is lag. I am sorry for wasting your time but I think this is NOT a wine issue.
I have this running in a .sh file everyime I load my DE,
id="pointer:Neo Reflection Neo Reflection Finger Mouse"; speed=0.778; xinput set-prop 8 "Coordinate Transformation Matrix" $speed, 0, 0, 0, $speed, 0, 0, 0, 1
I wonder if that is what is causing it, it used to not cause any issues before.
