mouse cursor lags in linux

[shubla]

On default client, there is great delay when moving it.

Painfully aware. For some reason, Java on X11 doesn't support more than 1-bit-color cursors, and therefore the client has to draw the cursor manually instead of having the window system do it, and it is therefore affected by input latency. Technically, input latency should be minimized, but doing so is somewhat difficult. It is something I am trying to improve in the rewritten client, however.

Why not, as many games have, add an option to use the system cursor?

If I understood correctly, that would mean black-and-white cursor that might look bit out of the place. However I'd prefer that to noticeable input lag.

If it really reduces input lag, some checkbox to do this would be nice.

It doesn't actually reduce input lag, it just exempts the mouse cursor from it. Arguably, the delayed mouse cursor is more "accurate", since clicks don't take effect until after the input latency has passed anyway.

What really should happen is that Java should support full-color cursors on X11. I have always expected this to happen any release now, and have no idea why that hasn't been the case.

Current fix for this is just to enable the 1-bit cursor. Its not that bad. For me, the normal cursor with many colors moves with 1-2 second delay, it makes the game literally unplayable as you can not even click things because coordination with cursor is difficult.

It actually is not black-and-white, but rather it chooses two dominant colors from the higher-color version of the cursor.

I'm pretty sure it's 2-3 frames. I don't disagree that it feels like a lot more, though.

It really is quite horribly bad, though.

I think in this case you also lose contextual cursor icon. I will rather play with 2 color cursor as I do now than system cursor only.

I have 10 fps in my village with a decent computer, because there are like hundreds of non-rotting sheep carcasses. So 2-3 frames does feel like a lot.
